You are asking for MCQ books that means you are already versed with your NEET context books. Now that's a good practice to revise your chapters and try out MCQs side by side..

My personal recommendations would be-

Objective physics, Objective chemistry and objective biology

Solving MCQs and going through study materials from monthly magazines like physics today, chemistry today and biology today will help you a lot.

However, special mention, MCQ sheets provided by Akash Institute (if you can collect them)will help greatly.

I wish you good luck!
