Hello Aspirant,

See If you are done with your syllabus of JEE-Main 2022 then solving Previous Year Questions, different Mock tests and sample papers is the best practice to get the thorough preparation of JEE-Main or any other competitive examination, so what I would recommend you is just solve one paper in a day in the fixed time of Three hours and don't go for next paper until you clear all your doubts of previous paper so the concepts will be cleared to you.

You can download different previous year's question papers and sample papers of JEE-Main from the link given below in Hindi language :-

As we know that now the aspirants are facing their last time preparation before JEE-Main examination so now the solving papers should be the main priority because at this point of time reading of full concepts and chapters won't be the wise strategy so just be focused on solving papers and some important chapters which have more weightage as compare to that of others and for your reference I have mentioned those chapters :-
