This can not be predicted exactly as the cutoff varies every year. But as per previous year trends for MAMC you need to score around 670 or above to get a seat in MAMC.
Talking about private candidates, The students who completed their class 12th from CBSE private exams or NIOS they are not eligible to appear for NEET 2019.

Hope this helps.

Thanks!!

The following is the cutoff for the OBC category students 118-678 rank and the marks are 635-674.Probably this is a reference you can plan accordingly as per this previous year scores.
