can you get 90 percentile in JEE main only by completing the syllabus and doing PYQs?

Dear aspirant,

Actually this is a very subjective question and I cant judge just on the basis of your completion of syllabus and doing previous years questions because I am not seeing what's your performance in the previous papers or how much you are scoring.

I would like to advise you to kindly also focus on solving mock papers because with these papers you would gain confidence and will get to know the pattern and the type of questions asked in the examination.

With these papers your nervousness at the final examination will decrease exponentially. Your time management , accuracy will be managed greatly. So, if you are scoring 130-150 in your mock papers then easily you can get 97 percentile in the mains examination.
