Dear aspirant

Important topics

1. Math - Calculus and geometry

2. Chemistry - Physical and Organic chemistry

3. Physics - Mechanics, Electricity

JEE mains exam covers almost the entirety of syllabus that they put up in the official syllabus. But, there are a few topics that would not require a lot of your time but would help you score well in JEE.

1. Environmental chemistry

2. Try and learn inorganic chemistry from NCERT as it requires you to remember certain things and can fetch you marks easily

3. Statistics (Math)- the questions are easy from this topic so you can easily score by learning a few formulae.

4. Communication system (Physics)

These topics are not important in the usual sense but if you focus on these, you will be able to answer questions with low effort and get good marks.

I wish you all the very best
