650 is a total Awesome Score. And that too if you have OBC reservation, then it's the best score you can aim for and get it done. You can get the best of colleges of India. If you apply through 15% ALL INDIA Quota, then you'll surely get a seat in top 5 colleges of India - first thing and secondly if you apply through 85% state quota, then you might definitely get the seat in best government MBBS college of you state.

As of now, if you are aiming for NEET 2020 or 2021, then stop thinking such marks and everything, be honest, focused and prepare well as of now and later on only think about these marks and everything.

Best wishes. Thank-you.
