The syllabus of JEE Main & Advanced exams is huge. it can take you at least 2 years to prepare for it and if you are no Mike Ross from suits. you need to revise from time to time to keep things in memory. when it comes to revision most people only start the day before the coaching exams and they just pick a topic randomly and start going through the class notes and some examples. but do you really think you need to revise the first law of motion ‘v = u + at‘. if you don’t know it by heart like 2 + 2 = 4 you are gonna have big problems. so most students end up wasting time over trivial formulas and trivial examples based on them.
Prepare Early, So you don’t waste time later

Jee exams are not a battle but a war fought over 2 years. let’s say you want to revise all the topics a week before the exam. what are you going to do? start from page 1 of class note 1 and go through 50 300-page class notes one by one. doesn’t sound realistic right? so prepare the material you want to revise in advance. I recommend creating a summary/short notes. that only contain the main points of a topic, very important formulas that you might forget, and some exceptions you have encountered in a homework problem or test. you should follow these three steps for creating short notes that are extensive but easy and quick to revise.
- After class, go through your day’s class notes and transfer all the important points and formulas to the short notes.
- While attempting questions, the reason of ones you can’t solve should be in short notes.
- After Test, reasons of the problem you can’t solve in the test should be in short notes.
Prepare collection of quality revision questions

Going through theory is simply not enough for revision. you should get your hands dirty with some practice questions too. but which one? for 1 topic you will have 100s of questions you tried as homework or test. most students just do the examples done in class. but they are too simple and for getting you a basic understanding of topic only. that’s why you should have a collection of quality questions that you can revisit while revision. every time you attempt a homework question, if you can’t solve it in one try and under 3 mins, mark a little start of something next to it in the material. similarly, for the questions, you encountered in the coaching test but couldn’t solve mark a start next to them. you can also include problems that you could solve but are tough and encapsulate a topic nicely. these starred questions become your topic-wise set of quality practice problems for you to revise. if while revising you can’t solve any starred problem include one more star to indicate this is where you face real problems.
Conclusion
The things I mentioned are very simple to implement in your day it will hardly take half-hour daily to do all of it. but later a week or a month before the JEE exams you won’t be blind wandering in the vast amount of knowledge and material you have collected over 2 years. you should have clear sight in mind from the beginning of all things you need before the exams and simply just start working on it day by day. once again JEE is not a battle but a war.
