📚 How to Tackle 47 Lectures in a Week
The narrator recounts a conversation with a cousin who has 47 lectures to study for an exam in just a week. He reassures the cousin that while challenging, it's possible with the right strategy. He explains that smart and effective studying can be done at any point before the exam, whether it’s 50 days or 5 days. He’s confident because he used to cram lectures at the last minute, but after developing and refining certain techniques, he now can go through hours of lectures in mere minutes.
📝 Step 1: Skim Through the Lectures
The first key step is to skim through one large lecture or a few related ones. This involves not taking notes but just getting a general sense of the material. He gives an example using a lecture on arrhythmia, explaining how to quickly identify key subtopics, like Bradycardia and Tachycardia, and their subtypes. The goal here is to understand how the topic is categorized, get a gist of the key subtopics, and decide whether additional resources are needed for deeper understanding.
📺 Step 2: Watch a YouTube Video for a Quick Overview
After skimming, the next step is to watch a short YouTube video related to the topic. In the example of arrhythmias, the narrator watches a video explaining the different types of arrhythmias and how they affect the heart's electrical pathways. This provides an easier-to-understand and visual representation of the material. He suggests categorizing the subtopics as you watch the video to make the topic more memorable and logically structured.
🗂 Step 3: Categorize Subtopics for Easier Recall
Step three involves writing down and categorizing the subtopics and keywords. By categorizing information (e.g., grouping arrhythmias based on location in the heart's electrical pathway), you force your brain to remember key details. For example, by linking atrial fibrillation to its location in the heart, one can easily recall related arrhythmias and their treatments. Categorizing information this way creates mental connections that make recalling details much easier.
🧠 Step 4: Create a Memorable Mind Map
In this step, the narrator suggests creating a detailed and memorable mind map. He emphasizes that it should not be a simple diagram but one that links concepts intuitively. For example, drawing the heart’s electrical pathway and labeling arrhythmias on the map helps to make the material more visual and memorable. This approach helps consolidate knowledge and makes it easier to understand and recall during future study sessions.
📝 The Benefits of a Mind Map for Complex Topics
Mind maps can be extremely helpful, especially for complex topics. The narrator discusses how mind maps simplify concepts by linking related subtopics. By visually organizing investigations, treatments, and scans on the map, it becomes easier to recall the information. The process of creating a mind map aids memory retention because the learner actively engages with and categorizes the material.
⏳ Efficient Studying Using Layered Learning
In this step, the narrator explains that after building a foundation with skimming and mind maps, the focus should be on layering information. Instead of forcing yourself to memorize everything at once, you focus on what you can understand easily. The harder details are tackled later, once more foundational knowledge has been built. The approach saves time and ensures a deeper understanding of the material, allowing for efficient studying.
❓ Step 5: Create Recall Questions
While studying, the narrator suggests creating recall questions to reinforce understanding. These questions should focus on key details and topics likely to be tested in exams. He also introduces a note-taking app called Xiles, which allows for an intuitive and flexible approach to organizing notes. The app is useful for creating questions, adding images, and organizing study material visually.
🔍 Step 6: Delve into the Details
Now it's time to review the detailed information that was skipped during the initial skimming. This step involves going back to the lecture slides and revisiting the harder concepts with a more solid foundation. You may even choose to re-watch parts of the lecture. The narrator emphasizes that studying should not be rigid—after the initial steps, you should aim to process the information in layers, gradually understanding more complex details.
📖 A Layered Approach to Studying Multiple Lectures
The narrator wraps up by encouraging students to use the same layering method for related lectures. By skimming multiple lectures and creating mind maps, you lay the foundation for those topics and can build on them together. He emphasizes that this approach will drastically reduce the time needed to study and ensure a much deeper understanding of the material.
🚀 Final Thoughts on the Study Method
The narrator concludes by reinforcing how effective the method has been for him. After skimming, mind mapping, and using the layering method, the time it takes to go through lectures is reduced significantly. He also promotes Xiles as a useful app for note-taking and mentions his live study sessions where he demonstrates these techniques in more detail.

Highlights
Smart, effective studying can be done at any point in the year, whether it's 50 days or 5 days before your exam.
The goal is to be able to go through 3 to 4 hours of lectures in just 20 minutes by using efficient techniques.
Step one involves skimming through one big lecture or multiple related lectures to get a general understanding without taking any notes.
Download the slides and use 'command F' to filter information, which makes understanding and categorizing topics easier.
Step two involves watching a short YouTube video to gain a general understanding of the topic and to establish a mental base.
Step three includes writing down all the subtopics and keywords that pop out during the lecture and categorizing them into sections.
Creating a mind map is the fourth step, making it as memorable and intuitive as possible by incorporating visual elements like diagrams.
The mind map helps create an initial mental base, putting all concepts into a memorable, interconnected structure.
When studying a topic, filter and only read the parts that you can easily understand—do not force understanding of difficult details immediately.
Convert all the information that needs to be recalled into questions during the study process for better retention.
By studying in layers and focusing on building an initial understanding, you make it easier to remember details later on.
For efficient note-taking, use tools like xTiles, which allows you to organize questions, add diagrams, and customize the format to enhance understanding.
Revisiting challenging content after understanding the basics allows you to absorb information more efficiently.
Creating mind maps for multiple related lectures helps in efficiently building a base for understanding interconnected topics.
By skimming first and creating a mental base, the method can significantly reduce the amount of time needed to study each lecture.
Transcripts
the other day my cousin came up to me
and went like bro I am so screwed my
exams are in a week and I have 47
lectures to do like what do I do and
what I told him was that 47 lectures is
tough but it's doable to be honest cuz
yes in this video I'm going to teach you
the simplest fastest way to study for
lectures but what I really wanted to
make clear is that smart effective
studying can be done at any point of the
year whether it's 50 days or 5 days
before your exam and if you do what I
tell you you will guaranteed understand
more information and in a better way
that you just read your lectures or made
some notes or did questions alone and
how am I this confident cuz a few years
ago I was the guy cramming in the
lecture slides last minute trying to
listen to them on two time speed skim
through the slides as much as possible
and it didn't work until I found these
techniques improved them and applied
them to my way of study which has now
led me to have the ability to go through
3 hours 4 hours of lectures in a mere 20
minutes so let's get straight into how I
study a lecture obviously we're not
watching the whole lecture right now
even if it's on two times speed that's
too much of a time waste download this
slides so you can quickly look through
them so you can command F filter the
information and make your life easier
and what you need to do and I've said it
before is that you need to start by
creating an initial base for the entire
topic which basically means just
breaking the entire topic down looking
at the subtopics seeing how you can
categorize everything in those subtopics
and linking them and finding a memorable
way to remember everything we'll be
doing that step by step in steps 1 to
four and then we'll go through the
lectures once and you will remember in
your head trust me this will quarter the
amount of time you study step one skim
through one big lecture or two to three
related ones if they're under the same
topic no notetaking right now just
skimming for example I'm bringing up a
pretty heavy lecture it's on arhythmia
I'm just going to flick through the
slides arhythmia basically are abnormal
rhythms of the heart and they can be
broken down as we can see here into
Brady cardas and takic cardas um I'd
look up any of the words if I didn't
know what they meant as I went through
but in the first few slides I can see
that it's just Basics about how the
heart works and how the electrical
signals in the heart conduct it's going
through AV blocks heart blocks uh and
then it's categorizing the different
Tachi cardas into um different sub types
and then as we can see the tacki Cardis
are being divided up into narrow complex
and Broad complex and then being listed
underneath I'm going to keep that in
mind for later because that's probably
helpful way to categorize the topic
remember I need to skim through this all
just to get a general gist of fit so
what that basically means is that you
need to take a very specific note right
from the start of how your topics and
subtopics are being categorized
throughout the slides or throughout
multiple lectures even but overall what
I need to do for this first step the
skimming I just need to go through
everything which is going to take 5 10
minutes to understand what subtopics are
I need to learn what's important how
much information is even on here do I
need more resources at this point my
second step would be to go watch a video
for most topics short YouTube videos are
a very fast way to get a general gist of
what everything is how it works what
arhythmia are for this video I just
pulled up it looks like this guy is
explaining them well he looks like he
might be explaining them via location
like so he's dividing the rhyas up into
the different electrical into where they
affect which part of the electrical
pathway of the heart they affect um and
that feels like a good way to think
about it and then after finishing this
video what I do is step three which
ideally should be done while you skim if
you want to be uh Ultra efficient but
step three involves first writing down
all the subtopics and keywords that pop
out during the lecture and second then
categorizing them writing down all the
subtopics and keywords and categorizing
them should be easy after all the
skimming and understanding we've just
been doing like the last 10 15 minutes
for example I think for these rhythmia
probably the smartest way to categorize
them would be by location in the
electrical pathway like that guy in the
YouTube video did so that's what I do by
categorizing the subtopics you are
forcing your brain to remember what is
underneath them you're way more like
need to remember things if you
categorize them if that makes sense now
for example when I see Atri fibrillation
what I'll think is okay super
ventricular tardia Supra above the
ventricles it is in the first two
Chambers so it's probably affecting the
electrical pathway in that area and then
once you remember this small detail
about the Atri fibrillation one by one
your brain will start remembering all
the other super ventricular T cardias
and all the associated information with
them their investigations their
treatments it's all linked now that
we've categorized all the subtopics and
keywords into different sections and we
thought about a nice way to think about
the me as by location now what we do to
solidify that initial base to fully
create and put it in front of us is by
creating a mind map and when I say mind
map I don't just mean putting a circle
in the middle and have 100 things coming
off it your job when you're making this
mind map is to make it as memorable and
as intuitive as possible for example
we've thought about all the arhythmia
Via location so what we could do in the
mind map is actually draw out the
electrical pathway of the heart on the
Mind map and then label the arhythmia on
the pathway and then after we've labeled
the arhythmia I then draw some of their
features out draw the Nar narrow complex
the broad complex draw the ECG of each
individual arhythmia or like some
memorable thing to do with it for
example like apib at flutter atra
flutter could be like a bird that small
diagram on it as well to symbolize the
flutter I don't know I would try and add
as many Concepts onto this mind map and
see where everything fit and by putting
it on here I just I just hope that you
see how memorable and easy it is and
intuitive the entire topic becomes for
you not to learn once everything is on
here you literally have every single
arhythmia that could possibly link to a
different part of the electrical pathway
and then you can remember it using that
in the future of course I picked an easy
topic to explain I've only mentioned the
basic classifications of arhythmia but
you can legit see how every hard concept
whatever it is investigations treatments
scans to do with each type of arhythmia
is on the Mind map everything that links
to each of the soft topics can go here
and that makes it so easy for you to
remember them because you made this mind
map you will remember the entire topic
through the categories that you put on
here and now when you think about each
arhythmia your brain will automatically
remember all the details of the
arhythmia because it's all on the Mind
map and then through that link you'll
also think about the other categories
the other arhythmia and remember those
details because your thought process has
link them all together so well you'll
think about the others in the same
thought what makes each thing different
what makes it similar and this applies
to every topic this entire thing will
Maximum take like 20 to 30 minutes to do
per topic and in this process you've
gone through the entire 90 slide lecture
you've skimmed it you've watched a video
you've gone through the basics and
you've thought about a solid way to
think and Link all of these arhythmia
together through a mind map and that is
the benefit of creating that initial
mind map that base and putting an effort
in the skimming by just spending 30
minutes at the start of your studying
and doing this youve made the rest of
your study piss easy now for the rest of
the study the way that you're going to
go through and read through the lectures
and all of the topic information is that
you're only going to try and read and
understand the topics that you can
easily take in I know that may sound
counterintuitive but hear me out reading
through the information shouldn't be the
hard part of the learning yet we make it
super hard for ourselves by trying to
force ourselves to read sentences and
stick them in in our head and memorize
them your knowledge can only be built in
layers like building blocks so far by
this that we've already laid a few
building blocks as our base while we do
we're doing the skimming the Mind
mapping Etc so now for example when you
look at these slides there's some bullet
points I can easily link and understand
with the features of tachic cardia
involving the AV node so this layer of
information can easily slide on top of
the foundation I've already built but
there's also sub bullet points on here I
can immediately tell that this above my
current level of understanding so I just
ignore it that is the rule you can
revisit it later once you've gone
through more of the slides once you've
understood more information at that
point it will make more sense to you
because you've added more building
blocks than to slide that detail on top
of and this is how you should go through
all of these slides at this stage by
filtering and only reading the things
that you can easily understand at this
stage basically don't waste time with
the details just go through the slides
and trust me it will be much faster now
that you did the skimming and mind
mapping in the first place this isn't
really a separate step but the way I
revise is by doing question questions so
this means while I study I need to
actually create recall questions and
that is why side by side while doing
step five and starting to study the
topic I will convert all the information
that needs to be tested and recalled by
me and that can be tested on exams into
questions on a Word document I do
usually just organize everything that I
need to do all the questions I have ET
on a Word document but recently I've
tried a very solid note taking app
called xiles these guys recently hit me
up to try out their app for not taking
and as soon as I started using it the
thing that stood out to me was how easy
it was to move whatever I want wherever
I want it's like moving and playing with
tiles I can write on my questions add
images add tables and whatever
configuration looks most aesthetic or
whichever is most memorable for me and I
can make it very quick which not that
many other desktop apps actually allow
you to do as you can see I made some of
the questions from one of my cases on
here out of the learning outcomes the
conditions diagrams like exactly where I
need them there's a side column for the
week topics as well and honestly no
taking wise it was very easy to use as
well I didn't need a tutorial or
anything I just got started and figured
figed it all out intuitively honestly no
complaints from my end it's a great app
and other than note taking there's so
many other templates on here for weekly
planning there's calendars habit
trackers you can use it for your
business um school projects basically
everything you need to try it out all
you need to do is create a free account
with xiles with the link in my
description so yeah check it out use the
link in my description use it for class
one day for example and let's get back
into the method the last step as you can
guess is now hitting the details and
what this will involve is now you going
through all of the stuff that you
skipped out which you could have either
made a note of or whatever on maybe even
actually going to the lecture at this
point and going to the slides and
listening to what the guy is saying and
listening to how he's explaining the
details that actually might be helpful
as well what I also wanted to clarify
was that you naturally won't be studying
in this like rigid way of only Concepts
then then only the details like you know
what I mean yes you need to First skim
then create the initial mental model
that is a must that is very vital for it
to happen in those steps but after that
you basically need to aim to go through
the information from your textbook from
your lectures in layers keep on
processing what you can easily
understand until you can finally
understand the details and then taking
the details in will be very easy as well
by waiting till you have a solid
foundation by revising the each of the
stuff in layers in those building blocks
and not forcing yourself to jump to the
details you're basically just saving
time another tip to make it more
efficient is that you should try and
skim and then create the mind maps for
multiple lectures that have like a
related topics that way you're laying
the base for all of these related topics
and then you can one by one build on the
layers for all of them together but
anyways that is how I process lectures
step by step this is everything this is
how I go through them the method gets
faster and faster the more you do it and
it will quarter the amount of time you
take to go through each lecture once you
start strictly skimming first building
the initial base the Mind map I honestly
did it like once or twice and I started
to see humongous differences with the
amount of I was able to remember anyways
check X Styles out for a great fluid not
taking app use the link in my
description I'll get a little bit of
Kickback if you sign up for this stuff
I'm going to link my live studying
Series where I basically live go through
how I do the whole layering thing and
how I do step five in a lot more detail
thank you so much for watching please
let me know if you have any questions
about the whole method again it's not
like my method I've just taken it from
other people combined it with how I do
it and like improved it over time so I
think it's very doable for the general
population or anyone as well because
it's just a smart way to go through
lectures rather than going through Slide
by slide one by one check my inst out
leave a like spam the comments do all
the usual stuff and I will see you in
the next one
