Takeaways

• 😀 Focus on your learning style (visual, auditory, kinesthetic) to improve study effectiveness.
• 😀 Time left for OSN preparation is less than 2 months, so plan your study time wisely.
• 😀 Prioritize topics that have been frequently tested in previous OSN exams (2017-2021).
• 😀 The key mathematical areas for OSN are Algebra, Combinatorics, Geometry, and Number Theory.
• 😀 Past OSN problems from 2002-2021 can help identify common topics and question types.
• 😀 Be prepared for surprises—new types of questions may appear, as seen with the 2021 KSNK (e.g., coloring problems).
• 😀 Repetition of learned material is essential for reinforcing concepts and improving retention.
• 😀 Regular practice of past problems will help you get familiar with the exam's format and difficulty level.
• 😀 Focus on mastering high-frequency topics and avoid spreading your efforts too thin.
• 😀 Stay consistent with your study schedule, balancing subject review and practice without overloading yourself.
• 😀 Aim for both efficiency and effectiveness—study smart, not just hard.

How long is left to prepare for the OSN based on the video script?

According to the script, there are less than two months left to prepare for the OSN, as the event is scheduled to take place from May 23 to May 25, 2022.

What are the three main learning styles discussed in the script?

The three main learning styles mentioned are visual (learning through reading or seeing), auditory (learning through listening), and kinesthetic (learning through hands-on experience).

How many times has the speaker participated in OSN, and in which years?

The speaker has participated in the OSN four times, specifically in the years 2011, 2012, 2013, and 2014.

What is the key challenge mentioned about preparing for the OSN with the limited time available?

The main challenge is that the amount of material to study for the OSN is very large, and it is impossible to cover all of it in such a short time frame.

What approach does the speaker suggest for selecting study material for the OSN?

The speaker suggests focusing on the topics that are most likely to appear in the exam, based on previous years' questions. Reviewing past OSN questions, particularly from 2017 to 2021, can help identify patterns and focus areas.

Which areas of mathematics are emphasized for OSN preparation in the script?

The areas of mathematics highlighted are algebra, combinatorics, geometry, and number theory.

What is the importance of reviewing previous OSN questions, according to the script?

Reviewing previous OSN questions is important because it helps identify recurring topics and question types, allowing for more efficient preparation by focusing on what is most likely to appear in the current year’s exam.

What unexpected topics appeared in the 2021 KSN that were not present in prior years?

In the 2021 KSN, there were questions on coloring, which had never appeared before in OSK, as well as difficult modulo problems that had not been seen in previous KSN exams.

What are the three key steps the speaker recommends for effective OSN preparation?

The three recommended steps are: 1) Focus on material that frequently appears in previous OSN exams, 2) Repeat the material that has already been studied, and 3) Practice solving problems to reinforce learning.
