dear student

for practicing previous year JEE questions I would recommend Arihant  publication books . It has errorless and detailed solution or go for  FIITJEE archive  

You can take JEE previous year papers online on Embibe.

hope it helps

All the best!!!

dear student,

There are two ways-
1) If you want only questions and intend to ask the problems which you coiuld not solve to your teachers, then go for FIITJEE Archive.
2) if you want topic wise short notes/summary as well as solutions/hints of the questions given at back, then go for ARIHANT. Also, Arihant has least error among these. Also, make sure that you see a solution only when you have exhausted your all options to solve that problem

I would personally recommend for option 2.

hope it helps!!!
