The Preparation Strategy

Though you know the chapter weightage for JEE Mains now, you need a plan of action, right? So, here is a short 5-step preparation strategy that you can follow:

1.   Focus on Conceptual Clarity

Many students make the mistake of rote learning formulae. While that might work for certain topics, the core of JEE Main lies in concept-based questions. Make sure you understand the ‘why’ behind every formula. Thus keeping your concepts clear on every major topic, you will be in a better position from the very beginning.

2.   Time Management and Regular Revision

Make a study timetable where you dedicate a significant portion of time to revising important chapters. Solving previous years’ papers and taking mock tests will help you get accustomed to time management during the actual exam. More importantly, learning time management during the exam itself besides knowing the chapter weightage for JEE Mains is also immensely important. So you need to focus on all these areas.

3.   Identify Weak Areas Early

It’s essential to recognise your weak points as early as possible. If a certain chapter is particularly challenging, seek help from mentors or peers, or even consider joining a coaching class or online forum. By appearing in the mock tests, your weak areas can also be identified. So, once identified, work rigorously on them to avoid exam difficulties.

4.   Practice with a Variety of Problems

Ensure that your preparation involves solving questions of varying difficulty levels. When getting ready for Maths (as well as other subjects), practice makes all the difference. Find all the solutions you can While it’s important to solve simple problems, you should also focus on higher-level problems that combine multiple concepts.

5.   Regular Mock Tests & PYQs

Mock exams and the previous year’s question papers (PYQs) are essential to succeed in JEE Main. They speed up your time, help you become more comfortable with the test format, and imitate the real exam setting. PYQs also shed light on popular subjects and patterns of questions. Timed mock exams should be taken, and the results should be analysed to see where you can improve.
