Hi Anu,

As far as questions bank are concerned, a lot of publishers are there whose books are great for practice and some for both practice and theory.

1. Universal self Scorer- This is a golden Book and have a mine of questions. The questions range from easy to difficult covering all the various topics and even the sub topics. A quick brief review and formulas are also given before the practice questions starts. This comes for all three subjects.

2. Dinesh publications- This publication house also has question bank for all three subjects. The questions are quality type and precise for NEET practice.

I hope it helps

All the best!
