In Physics, remember all the standard formulas. As I mentioned earlier, this paper is a test of speed, so it doesn’t matter that you can derive the formula because you will not have time to derive it in the exam. Make a list of every formula in a sheet, and read it very frequently. This will help you to memorize it. You should also solve enough questions related to any formula so that you get a very strong idea how to apply it and try to solve until you get the final answer. It is a very bad habit to leave the solution in middle thinking that, beyond that part of the solution it is very easy.
As for the study material, you can use the following:
- NCERT for reading purposes. A couple of questions also come from the electronics portion which is hard to understand for most of the student. So you can refer to the NCERT for it, don’t need to go beyond that. Previous years’ questions also help a lot.
- C.Vermais also a pretty helpful book. You can use it as a reading material and for solving its questions. Mains questions have almost the same level as HCV questions. So, try to solve all its problems and examples.
- If you are currently in any coaching institute then solve all the DPP (Daily Practice Problems) regularly. If you are not, then you can refer to any one of the books available in the market for JEE Mains.
- MTG magazines have also a very nice collection of notes, papers and different types of puzzles related to your course which will make your studies very enjoyable.
- JEE Main question papersare the must. You should solve every problem at least twice. Every year there are at least 7-8 questions which are directly from previous years’ papers. If you solve them quickly then you will save both, your energy and time which can be used for other questions.
The study materials discussed above are far more than enough. NCERT, HCV and JEE Main question papers are enough. Rest of them are for fun, and should only be used when you have extra time.
