Hello aspirant 

Yes you can get a private college for mbbs under neet marks , infact that is the only way you can get a mbbs college.

There are two types of medical private seat-

1 management quota -they ate fully paid private seats and Are easy to get because of their high fees not many candidate are willing to take it .

2. Government quota -they are private seats under government quota , they are competitive and the merit is comparatively higher as the fees is less.In order to get admission in this quota you need to have to get a good score.

All the best
