Hello Raju,

Going by previous year and the years before that, marks above 650 should have been enough

But this year, and from now onwards, the trends have and are going to change

The general cutoff for MAMC w/o DU quota was 676. 

I would say that a score of 670+ at least is needed to have measurable chances to get into MAMC this year for general candidates. So, you have some chance.

For VMMC, it is the second best choice after MAMC. So it gets filled up even before 100 AIR in NEET which means a score of more than around 630–640(for outside Delhi people in general category). So you have a better chance of getting a seat in this college.

Good luck!
