Hi Aspirant!

By observing the several year trends and cutoffs we can predict that with 160+ marks you can easily score 99 percentile and for this you can bifurcate your marks for each of the three subject according to your preference.

Hence, to get that marks you have to study well by taking organise steps.First you have to understand the concept then do the ncert ques then some good JEE book question or Previous year ques. And when the exam gets closer you should cover each and every concept according to cutoffs so that you can score 160+ start doing paper and only papers.

I hope it helps!
