play00:02

hi everyone my name is matt williams i'm

play00:03

the access fellow here at jesus college

play00:05

at the university of oxford

play00:06

i have been asked by a few commenters to

play00:09

update my tsa

play00:10

video the thinking skills assessment

play00:12

video i'll link the old ones

play00:14

up here so check those out if you

play00:15

haven't seen them already but i'm very

play00:16

happy to do so thank you so much for the

play00:18

comments do keep them coming i'll try

play00:19

and respond as quickly as i can

play00:22

one update that's really important is

play00:23

that this year 2020 of course there's

play00:25

going to be some significant

play00:26

changes as a result of the coronavirus

play00:28

pandemic one of the most

play00:30

impactful changes is that you will no

play00:31

longer have a physical paper copy of the

play00:34

tsa to work from

play00:35

and that means that some of the

play00:36

annotations that i suggested in previous

play00:38

videos

play00:39

won't work so easily so i'll explain

play00:41

some of my techniques as to how you can

play00:43

transfer the annotations onto another

play00:45

writing medium that you will be allowed

play00:47

to have either a piece of paper or a

play00:48

little white board next to you

play00:50

at the test center so that's one thing

play00:53

to bear in mind

play00:54

the other thing is just to emphasize

play00:55

some of the top exam technique tips that

play00:58

i provide in the other

play00:59

videos and i think one of the key things

play01:01

to stress is how much

play01:03

the tsa test tests your intellectual

play01:06

stamina it doesn't just test how smart

play01:09

you are

play01:10

in fact i think even more than testing

play01:12

your ability to solve problems and think

play01:14

critically

play01:15

it tests how you can do that under a

play01:17

sustained amount

play01:18

of intellectual pressure it is a

play01:21

marathon in other words not a sprint

play01:23

and that has all sorts of implications

play01:26

for how you treat

play01:27

your mind in the preparation for the

play01:29

test and most importantly that means

play01:32

that you need to look after yourself

play01:34

that when i've done admissions

play01:36

using the tsa test in oxford so that's

play01:38

mostly for the philosophy politics and

play01:40

economics degree ppe

play01:42

i've seen that the difference between

play01:43

being in the top

play01:45

quartile and the second quartile comes

play01:47

down to a fraction of

play01:49

one percent tiny tiny differences and it

play01:51

really

play01:52

therefore could make the difference

play01:53

whether you tip over into that top

play01:55

quartile or not

play01:56

as to how fresh you're feeling because

play01:58

if you're going through a test of

play01:59

intellectual stamina you need to make

play02:01

sure that your

play02:02

mind and body are at their peak and so

play02:04

that means you need to be very well

play02:06

rested

play02:06

you need to sleep and you need to eat

play02:08

well and you need to drink plenty of

play02:10

water

play02:11

these physical and physiological

play02:14

factors make substantial neurological

play02:17

difference and therefore you really need

play02:19

to take consideration of them

play02:21

another consideration is how to work out

play02:24

the most efficient way of answering the

play02:25

questions certainly the multiple choice

play02:26

components section one of the tests

play02:28

and so i'm going to share with you some

play02:29

of my tips as to how to maximize that

play02:31

efficiency

play02:32

so you can get through the questions

play02:33

nice and quickly i'm going to go through

play02:35

the

play02:36

five finishing questions of the 2019

play02:40

tsa section one the reason for going

play02:42

through the last five questions is

play02:43

because a lot of people suspect that the

play02:44

finishing questions are the most

play02:45

difficult

play02:46

actually if you go and look at the

play02:47

weighting of the questions which is all

play02:49

provided on the oxford university

play02:50

website you'll see that

play02:51

the difficulty of questions is randomly

play02:53

distributed around the paper so it's not

play02:55

the case that the later questions are

play02:57

more difficult than the earlier ones

play02:58

but i suspect that the later questions

play03:00

certainly feel harder because by that

play03:03

stage

play03:03

you're knackered you're just tired and

play03:05

that's completely understandable

play03:07

so i'll go through those last five uh

play03:09

just to share some of my tips as to how

play03:11

you can get through them more quickly

play03:13

i'll then quickly go through section two

play03:15

just to remind you some of my top essay

play03:17

writing techniques

play03:18

and that'll be that so i'm going to

play03:20

share with you

play03:21

my ipad screen okay so let's start with

play03:24

question number 46.

play03:25

now one of my first tips with regard to

play03:27

maximizing your efficiency is always to

play03:29

start by reading the prompt

play03:30

the question before reading any of the

play03:32

other extraneous information

play03:33

because then you know the task that's

play03:35

expected of you it's just a bit more

play03:36

efficient

play03:37

because what will often happen is that

play03:38

you'll read the information then read

play03:40

the question and then you'll have to

play03:41

read the information again

play03:42

it just cuts out that component for the

play03:45

most part

play03:46

so which one of the following most

play03:47

closely parallels the reasoning used in

play03:49

the above argument

play03:50

now this little question crops up

play03:52

earlier and one way to

play03:54

help yourself with this is to formalize

play03:57

the

play03:58

form of argument that you've got here

play03:59

now this is common in formal logic

play04:01

and it's the sort of thing that

play04:02

philosophers do it's not terribly

play04:04

complicated however so i'll just show

play04:06

you how to do it

play04:07

so your cake will be tasty only if you

play04:09

use fresh ingredients

play04:11

which you can only buy at the market you

play04:13

did not go to the market so your cake

play04:15

will not be

play04:15

tasty now this is a type of argument

play04:18

along the lines of

play04:21

not p therefore

play04:24

three dot triangle is therefore not

play04:28

q okay now why philosophers like p

play04:31

and q i don't know but they do you can

play04:34

use whatever letters or symbols you like

play04:36

but it makes it relatively clear now the

play04:38

examiners are looking for the same

play04:39

type of argument if not p therefore not

play04:42

q

play04:43

it could be tempting to say that other

play04:45

arguments where you have p

play04:46

and therefore have q are the same form

play04:48

of argument but according to the logic

play04:50

of it

play04:51

they aren't so be careful with that for

play04:53

example if we look at

play04:54

a you can only be happy if you are

play04:56

healthy to be healthy you have to eat a

play04:57

lot of vegetables you eat a lot of

play04:59

vegetables

play04:59

so you must be happy now that's a form

play05:01

of argument along the lines of

play05:03

p therefore q

play05:07

and it's tempting to say that that's

play05:08

basically the inverted logic of

play05:10

the cake argument but that's and that is

play05:13

precisely true but it's inverted logic

play05:15

and therefore it's not the same form of

play05:17

argument so in my first reading through

play05:19

these questions i thought

play05:20

it might be a but actually on thinking

play05:23

about it more carefully

play05:25

it's not the same form the examiner's

play05:27

statement about cakes is if not

play05:29

p therefore not q and a is p therefore q

play05:32

okay so just be careful with that so we

play05:34

can we can dismiss a

play05:36

b she only went to school or to the

play05:38

playground she's not in the playground

play05:39

so she must have gone to

play05:40

school so this is a case of not

play05:44

p therefore q

play05:48

which is again not the same form of

play05:49

argument see

play05:51

if you light a candle there is light and

play05:52

if there's light i'm able to reach you

play05:54

you must admit to candle because i can

play05:57

read so this is the case of p

play05:59

therefore q you lit a candle that i can

play06:01

read

play06:02

so let's not see listening to loud music

play06:05

through earphones damages hearing his

play06:07

hearing is fine which means that he must

play06:08

not have

play06:08

listened to loud music through earphones

play06:11

so this is a case of

play06:12

not p therefore

play06:15

q and then finally good knowledge of the

play06:19

car is necessary for fixing it

play06:21

without fixing the car we will not

play06:22

arrive at the wedding in time we will

play06:24

surely be late

play06:25

we do not have good knowledge of the car

play06:27

so not

play06:28

p therefore not

play06:32

q and so e is the answer because it is

play06:34

the only one

play06:36

that is the same form of argument as the

play06:39

original argument okay so hopefully that

play06:42

makes sense

play06:43

i can see how confusion easily emerges

play06:44

because i was easily confused by this

play06:46

but if you formalize it if you think in

play06:48

logical terms

play06:49

i think it makes things a lot clearer

play06:52

okay so that's question

play06:54

46 let's go to question 47 and question

play06:56

47

play06:57

is a critical thinking question and

play06:59

again start by reading the question

play07:01

don't uh waste your time by reading all

play07:04

of this

play07:05

and then read the question and then read

play07:07

it all again because

play07:08

that's part of what will contribute to

play07:10

your fatigue and you want to be as

play07:11

efficient as possible

play07:13

okay so which one of the following

play07:14

illustrates the principle used in the

play07:16

above argument so we're looking for the

play07:17

principle

play07:18

okay so we can write down

play07:21

principle on our piece of paper

play07:25

and once we've found the principle we

play07:27

don't necessarily need to read anything

play07:28

else

play07:29

so be fairly confident once you distill

play07:31

the essence of what's being said

play07:33

you can kind of move on because the

play07:35

examiners will put in a lot of

play07:37

fluff a lot of filler in order again to

play07:39

just waste your time and to make you

play07:40

feel fatigued so once you've worked out

play07:42

the principle you can probably move on

play07:44

so let's read it costs of health care in

play07:46

the uk are

play07:47

shared through taxation but some of

play07:49

those who can afford to pay for a higher

play07:50

standard of care choose to do so

play07:52

some think it is immoral for rich people

play07:53

to receive better health care simply

play07:55

because they can afford to pay

play07:56

pay for it but the whole point of money

play07:59

is to enable those who have it to

play08:00

improve the quality of

play08:02

life of themselves and their families

play08:05

the whole point now there's not much

play08:06

more of a giveaway than that that this

play08:08

is the essence of the argument the

play08:10

principle

play08:11

so the principle i would say is that

play08:14

money

play08:14

enables now again you can't write on

play08:17

your

play08:18

exam this year because of

play08:21

covid but you can write principal equals

play08:24

money enabled

play08:25

now we could reach to the end if we want

play08:27

uh but you know if you're getting

play08:28

towards the end of the paper and you're

play08:29

running out of time

play08:30

you may just simply want to move on to

play08:32

reading the five options but let's just

play08:33

read to the end quickly

play08:35

um if money did not offer such

play08:38

advantages it would not motivate people

play08:39

to develop

play08:40

their skills or to work harder in order

play08:42

to earn more since people are morally

play08:43

entitled to use their money to buy

play08:44

advantages for themselves and their

play08:46

loved ones

play08:47

there can be no objection to private

play08:49

medicine

play08:50

so which of the following illustrates

play08:52

the principle used

play08:54

so we're looking for the principle that

play08:55

money is enabling all right

play08:57

so a people who have been born rich

play08:59

should not waste their inherited wealth

play09:01

in gambling self-indulgence and

play09:02

extravagant living

play09:04

no that's not the principle b it is a

play09:06

good thing for people from rich

play09:07

countries to take foreign holidays

play09:09

because the income generated below value

play09:10

but no

play09:12

see people who are born talented are

play09:13

under a moral obligation to develop

play09:15

their talents

play09:16

no so you don't really need to read the

play09:19

whole

play09:20

prompt and that could actually waste

play09:22

your time if you tried

play09:23

d rich people should give away some of

play09:24

their wealth to benefit those less

play09:26

fortunate than themselves

play09:27

no the inheritance tax should be set at

play09:29

a fairly low rate so that the children

play09:31

of rich parents inherent enough money to

play09:32

make a substantial difference to their

play09:34

lives

play09:34

now i'd say e is closest to the

play09:36

principle that money

play09:38

is enabling of choice of of empowerment

play09:43

okay so e is the correct answer

play09:46

all right so question 48 is a

play09:49

problem-solving question meaning that

play09:50

it's a more mathematical

play09:52

question and again you can with these

play09:55

ones even read

play09:56

the question first just so that you know

play09:57

what you're hunting for so that you're a

play09:59

bit like a detective who knows what

play10:00

murder weapon they're searching out

play10:02

so in which day am i going to have the

play10:03

necessary amount of sourdough so we're

play10:05

looking for a specific day

play10:07

okay and we're looking for an amount of

play10:10

sourdough so it's useful to know what

play10:11

the amounts of sourdough are

play10:13

we've got a sense of the key variables

play10:14

in this question quantity of sourdough

play10:17

number of days okay any other variables

play10:20

are therefore somewhat extraneous

play10:21

so even before reading the information

play10:23

we know what data we need to extract

play10:26

i think that's quite a sensible way of

play10:27

going through it because there is so

play10:28

much data given

play10:29

too much data given deliberately in

play10:31

order to tie you out so if you want to

play10:32

maximize the efficiency

play10:34

of your of your stamina then that could

play10:36

be a good way of doing it

play10:37

anyway so let's go through it sourdough

play10:39

an ingredient of many bread products

play10:41

is a fermented mixture of flour and

play10:42

water i mean that's an example that's

play10:44

pure filler you don't need to read that

play10:45

at all

play10:46

but it's there just to sort of draw some

play10:49

more of your intellectual energy

play10:51

at eight am on monday morning i start

play10:52

with a mixture of 50 grams of flour and

play10:54

50 grams of water

play10:55

each morning at 8 a.m i double the

play10:57

weight of the sourdough by adding equal

play10:59

weights of flour and water

play11:00

i know that one gram of water content

play11:02

evaporates every hour

play11:04

the bread recipe that i would like to

play11:05

use requires 550 grams of

play11:08

flat sourdough i also want at least 50

play11:10

grams of sourdough left over so that i

play11:12

can continue growing for next week's

play11:13

bread

play11:14

so which day am i going to have the

play11:15

necessary amount of sourdough

play11:17

so we now know that necessarily the

play11:19

necessary amount of

play11:21

sourdough is 550 grams and we're trying

play11:23

to work out

play11:24

on what day that much is produced given

play11:27

that the amount doubles

play11:28

daily so let's write it again in some

play11:31

quite formalist

play11:32

formalized terms so that we get a clear

play11:35

sense

play11:36

of what's going on so on monday morning

play11:38

i start with a mixture of

play11:39

50 grams of flour 50 grams of water

play11:44

and one gram of the water evaporates

play11:47

every hour

play11:47

so in a 24-hour period we lose 24 grams

play11:50

meaning that we have a total amount

play11:52

of 50 plus 50 was 100 minus 24 which is

play11:55

76 grams so on tuesday there are 76

play11:58

grams

play12:00

okay and

play12:04

each morning at 8 am i double the weight

play12:06

of the sourdough

play12:08

okay by adding equal weights of flour

play12:10

and water now we don't necessarily need

play12:11

to worry about the equal weights of

play12:12

flour and water we just need to know

play12:14

that it's doubled

play12:15

in scale so it's 76 grams multiplied by

play12:18

two

play12:19

and we know that of that 24 grams are

play12:21

going to disappear through evaporation

play12:23

so 76 times 2 is 140 152

play12:28

minus 24 is 12828

play12:31

grams so on wednesday we've got

play12:35

128 grams which is doubled

play12:38

minus 24. so 128

play12:42

times two is 256. minus 24.

play12:46

solutions to my mental arithmetic here

play12:48

is

play12:49

uh 252 232

play12:52

okay like that so on thursday now again

play12:56

if you're really

play12:57

struggling for time you've probably done

play12:59

enough maths now because

play13:01

you know that it's doubling

play13:04

minus 24 every day so we know that the

play13:07

answer can't be thursday but we know if

play13:08

you double 232

play13:11

and you're gonna get uh

play13:14

400 over 400 and that's going to be

play13:17

doubled again on friday so you know that

play13:18

it's got to be friday that you're going

play13:19

to get over 550 grams so

play13:22

if you're getting short on time you

play13:24

don't really need to do all of the

play13:25

mathematics but i'll just go through it

play13:27

just to be clear so 232 grams multiplied

play13:29

by 2 because we're doubling weight and

play13:30

then we're losing 24 grams

play13:32

so that's 464

play13:38

464 minus 24 is

play13:42

440 so that means that on friday

play13:46

we're going to double it again 440 grams

play13:49

multiplied by 2 minus 24 and we know

play13:52

that we don't even need to do that final

play13:53

mathematics but we know that

play13:55

that is greater than 550.

play13:58

so the answer has to be friday okay

play14:01

so let's move on to question 49 and

play14:05

again i would suggest you start by

play14:07

reading the question

play14:08

what is the largest possible peanut

play14:10

content of the nuts remaining in the bag

play14:12

after i've eaten all the almonds so we

play14:13

know that we need to concentrate our

play14:14

fire on peanuts and almonds

play14:16

again the examiners are going to throw

play14:18

loads of information in your face

play14:19

they're going to try and put you off

play14:20

they're

play14:20

going to try and distract you you only

play14:22

need to focus really on peanuts and

play14:23

almonds okay

play14:24

so a 250 gram bag of mixed nuts

play14:28

this the contents of the packet as

play14:29

follows

play14:32

as they are my favorite i eat all the

play14:33

almonds in the packet and re-weigh it i

play14:35

find that the almond content was the

play14:36

minimum it could have been whilst being

play14:38

consistent with labeling

play14:39

what's the largest possible peanut

play14:41

content of the nuts remaining in the bag

play14:43

after i've eaten the almonds okay

play14:45

so we need to work out the weight of the

play14:47

bag after eating the almonds

play14:49

so the bag starts at 250 grams

play14:53

the album content was the minimum it

play14:55

could have been so that's 20

play14:56

so we're looking for 20 250

play15:02

uh which is 50 grams okay so without the

play15:05

almonds the bag weighs

play15:07

200 grams okay now we know that the

play15:09

peanut content of the nuts remaining bag

play15:12

was the largest possible okay

play15:15

so we've got 40 of the original bag

play15:20

not the new 200 gram bag but the

play15:21

original brag

play15:23

is peanuts so 250 grams

play15:26

40 thereof is 100 grams

play15:30

so we know that 100 grams of the newly

play15:32

reduced bag without the almonds

play15:34

is peanuts which is half right because

play15:37

the 200 gram bag uh

play15:40

divided by 100 is equal to

play15:44

half okay and so the answer must be c

play15:47

so again just go through it

play15:48

systematically

play15:50

work out what data you need and also

play15:52

what data is extraneous that the

play15:54

examiners are trying to just throw in

play15:55

your face and distract you with

play15:57

and move on okay as ever these sorts of

play15:59

puzzles are pretty straightforward if

play16:00

you've got

play16:01

all the time in the world but it's the

play16:03

stress and the fatigue that tend to

play16:06

drag you down at this later stage of the

play16:08

exam and so it's

play16:09

finding those techniques to speed up the

play16:11

process to be more efficient and to stay

play16:13

calm

play16:13

that's what we're looking for okay now

play16:15

question 50 is a spatial

play16:17

reasoning question these are the sort of

play16:20

questions i really hate i really

play16:21

struggle with

play16:22

bending these shapes in my mind

play16:26

but again there are ways that you can

play16:27

make your life a little bit easier so

play16:30

you could read the question first but i

play16:31

mean there's a little writing here it's

play16:33

not a big deal

play16:34

the net below can be folded to make

play16:36

roman at numerical dice

play16:37

which one of the following dice could

play16:39

have been made as a result of the

play16:41

folding the net okay so again to start

play16:44

with the information that you know

play16:47

you know that there has to be

play16:50

an arrangement of the numbers four and

play16:52

one

play16:53

such that four and one are in alignment

play16:56

with each other

play16:56

and you know the same must be true of

play16:58

three and six

play17:00

so when we're trying to work out how the

play17:02

other numbers will align at least we've

play17:03

got

play17:04

some polarity we've got and we've got a

play17:06

vector if you like

play17:07

okay and we know that relative to one

play17:11

and uh four that there's got to be

play17:14

a 90 degree turn so if we're looking for

play17:18

where

play17:18

two is relative to four it's got to be

play17:21

switched

play17:21

90 degrees in a clockwise direction and

play17:24

then we know that there is another

play17:27

90 degrees angle here

play17:31

another one here and another one

play17:36

here sorry this is really terrible

play17:41

uh drawing but uh anyway hopefully you

play17:43

get the point but there are

play17:44

490 degree angle so if if one and four

play17:47

are in in an alignment

play17:50

then we know that two is going to be

play17:54

90 degrees off three and six will be 180

play17:58

degrees and 270 degrees

play18:00

and then five will be 360 degrees so

play18:02

five will be the same alignment as one

play18:04

and four

play18:05

okay so now when it comes to looking at

play18:07

the options

play18:09

well let's start with the simple array

play18:12

so we know that one and four must be

play18:14

aligned we know that screen six must be

play18:16

aligned so look for any examples where

play18:17

that could be the case

play18:19

so one and three no one and four

play18:22

here you can see are not in alignment so

play18:25

you know that b

play18:26

is wrong uh we know that a is wrong

play18:30

uh c one and three not sure yet

play18:33

okay d one and four are in alignment one

play18:36

is above the four so that's right and we

play18:38

also know that five must have gone

play18:40

through a 360 degree rotation

play18:42

so d must be correct okay

play18:45

there you go so there are various tricks

play18:48

that you can

play18:49

use to try and make this easier i mean i

play18:52

did say if you're given

play18:53

paper you could if you really wanted to

play18:56

tear it up and fold it into a dice

play18:58

but uh it's not strictly necessary okay

play19:01

let's go through section two so what are

play19:03

my key tips for this is the essay and

play19:05

this again is from the 2019 paper

play19:07

now as i've written in my previous

play19:09

videos on the tsa essay they go into a

play19:10

lot more detail

play19:11

the first thing is you need to know what

play19:13

you need to say in order to answer the

play19:15

question precisely

play19:16

one of the things that examiners really

play19:18

dislike is when students don't

play19:20

actually answer the question and the

play19:22

best way to ensure that you're answering

play19:24

the question is to

play19:25

literally reuse the question wording

play19:26

when framing your response

play19:28

and that will also help you identify

play19:30

what i call the hook words of the

play19:31

question which is the parts of the

play19:32

question

play19:33

which you need to address in order to

play19:36

satisfactorily answer the questions

play19:38

so let's start with the first question

play19:39

should children strike to demand action

play19:41

on a major issue such as climate change

play19:43

now if i was asked that in person if i

play19:45

was to respond precisely without

play19:47

deviation at all

play19:49

from the question i would have to say

play19:51

yes children should strike to demand

play19:53

action on a major issue such as climate

play19:54

change or no they shouldn't or whatever

play19:56

response they want to give the word

play19:59

should is clearly doing a lot of the

play20:01

spade work it's one of the first words

play20:02

that comes out and that's not

play20:03

surprising because it's one of the

play20:05

primary verbs okay

play20:07

and so should is one of is the hook word

play20:09

here

play20:10

you need if you're to answer this

play20:11

question properly you need to explain to

play20:13

someone what it means

play20:14

to should do something should it strike

play20:18

and so should is going to form

play20:21

the backbone of your argument and so you

play20:23

want an introduction where you answer

play20:25

the question very clearly and we're

play20:26

going to say

play20:27

do answer the question in the

play20:28

introduction do not mess around

play20:30

indeed you should answer the question in

play20:32

your opening line imagine you're

play20:34

in a conversation with someone you ask

play20:35

them a question and they don't answer

play20:37

the question until

play20:38

30 minutes have elapsed it's going to be

play20:41

quite frustrating

play20:42

answer the question in the opening line

play20:45

okay

play20:46

and then structure your argument around

play20:47

the word should so you need to break

play20:49

your

play20:49

paragraphs down into considering

play20:52

different aspects of

play20:53

should now a classic dichotomy would be

play20:57

should in a deontological sense

play21:02

and should in an instrumental or

play21:04

utilitarian sense

play21:06

and what that means is that should you

play21:08

do something because it's just right to

play21:10

do it it's intrinsically a good thing to

play21:12

do it doesn't really matter what the

play21:13

consequences are

play21:14

versus should you do something because

play21:16

it will lead to better outcomes

play21:18

so should children strike they should

play21:20

strike because striking

play21:22

is a good thing it's an intrinsically

play21:23

good thing because it shows their

play21:26

protest it shows their anger their sense

play21:29

of desperation

play21:30

it doesn't really matter what the

play21:31

consequences are and should because it

play21:33

will actually

play21:34

move things forward it'll progress the

play21:36

debate it'll make people realize how

play21:38

much needs to be done

play21:39

so that you can you can talk about

play21:41

should in both of those dimensions and

play21:43

it you can pretty much always define

play21:44

should in those two terms

play21:46

and of course you can you can link them

play21:48

together that

play21:49

the the reason that children should

play21:52

express themselves they should strike

play21:54

is because it will help make a

play21:55

difference and even if it doesn't have

play21:58

direct

play21:58

utility even if it doesn't make a direct

play22:00

difference it can contribute to wider

play22:02

debate that might

play22:03

make a difference so it's not like we're

play22:05

trying to completely separate out

play22:08

the deontological and the utilitarian

play22:10

but

play22:11

it can be quite a useful way of taking

play22:13

steps through the essay which will make

play22:15

sense

play22:15

okay so that's my key piece of advice

play22:18

for the essays is identify the hook word

play22:20

and for goodness sake use it use it and

play22:23

use it and use it

play22:24

don't use synonyms don't deviate from

play22:26

the question wording

play22:27

because then you're not answering the

play22:29

question the key

play22:30

the key thing to remember for yourself

play22:32

in the essay is

play22:34

you must answer the question the whole

play22:36

question and nothing but the question

play22:38

okay because otherwise if you deviate at

play22:41

all you're just giving the examiners

play22:42

the opportunity to mark you down and you

play22:44

don't want that okay so question number

play22:46

two

play22:47

assume that automated face recognition

play22:49

technology is completely reliable

play22:51

what restrictions if any should there be

play22:53

on its use so again if someone asked you

play22:54

that face to face

play22:56

you would have to start by saying well

play22:57

the restrictions that there should be

play22:59

are blah so the key words the hook words

play23:02

are

play23:02

restrictions and should okay

play23:06

so again you could you could think about

play23:08

should

play23:09

and break that up but i think sort of

play23:11

restrictions is perhaps more

play23:13

obviously what we need to be talking

play23:15

about

play23:16

and so you need to deconstruct the

play23:18

notion of restriction

play23:20

so that you can define it deconstruct

play23:22

means that imagine restriction as a

play23:24

concept as a building you're going to

play23:25

take the bits of the building off to see

play23:27

how it's put together

play23:28

so you could think of restrictions in

play23:30

terms of

play23:32

legal moral

play23:37

economic maybe now

play23:40

when you've worked out how to

play23:41

deconstruct a concept work out what

play23:44

logical sequence they could go in now i

play23:46

would suggest that

play23:47

moral is probably the most important

play23:49

because that's

play23:51

the the broadest so if you imagine a

play23:53

funnel we're going for the broadest to

play23:54

them to the narrowest

play23:56

moral probably comes first than legal

play23:58

then economic

play23:59

i would suggest very simply put it also

play24:02

means that the law is derivative of

play24:05

morality and economics

play24:06

derivative of law so you've got a

play24:08

logical sequence if we go

play24:10

moral restrictions legal restrictions

play24:14

economic restrictions and having that

play24:17

sort of logical progression of points

play24:19

really helps your readers because they

play24:21

can understand they can follow the story

play24:23

if you jump around from point to point

play24:25

as if you're hopping over stepping

play24:27

stones it's very confusing

play24:28

so at all costs try and avoid that okay

play24:32

so okay we can talk about those sorts of

play24:35

restrictions

play24:36

uh could somebody choose to change their

play24:38

race so

play24:39

again if someone's asking you about face

play24:41

to face the key word is could

play24:43

it's not should it could if you talk

play24:45

about should you'll get

play24:46

a bad mark okay the examiners are very

play24:49

precise to the degree

play24:50

to the point of being pedantic and you

play24:53

need to be pedantic as well

play24:54

so could this is potentiality and could

play24:57

here is the

play24:59

um is the hook word so could in the

play25:01

sense of

play25:02

is it i suppose you could talk about

play25:05

biologically feasible

play25:08

but then you could also talk about

play25:09

sociological

play25:12

in other words it's what extent is race

play25:15

a construct

play25:16

of sociology that differences in skin

play25:19

color

play25:20

are so irrelevant that they're as

play25:22

irrelevant as differences in eye color

play25:23

or hair color

play25:24

so someone could change their race

play25:27

insofar as they could

play25:28

change the very conversation about race

play25:30

and they could even sort of transcend

play25:32

race

play25:32

uh if if you like so once you've

play25:35

deconstructed could you can

play25:37

deconstruct your argument you can come

play25:39

up with a more

play25:40

segmented argument and you can work out

play25:43

a logical construction

play25:44

i think it's fairly reasonable to start

play25:46

with the biological and then go on to

play25:47

the sociological because of course

play25:49

anything about human society is

play25:51

derivative to some extent from our

play25:53

biology

play25:54

so could somebody choose to change their

play25:56

race you could argue

play25:57

uh they could in biological terms

play26:01

and they could in sociological terms or

play26:03

they could knock on both senses it's up

play26:04

to you to decide what argument you'd

play26:06

like

play26:07

okay finally number four should the main

play26:09

objective of a business be to make money

play26:11

it's up to up to you how to work that

play26:36

out but somehow you need to deconstruct

play26:38

should and then go through your

play26:39

deconstruction in a way that makes

play26:40

logical sense

play26:41

hopefully that's clear if you do have

play26:43

any follow-up questions do please either

play26:45
