What is a familiar and useful website there I can find questions and answer for NEET?

there are many platforms now avialable on internet when you can just scroll and get detail information related to studies.

Through EduRev Forums, you get a direct access to all the important questions pouring in from different parts of the country. Some questions might confuse at times but that’s what the preparation is all about. Interestingly, you have like-minded peers in these discussion groups with which you can discuss the possibilities of a solution to a question. Even teachers contribute in the discussions at times.
