if you are from the scheduled caste category let me tell you that has got the last year Maulana Azad medical College had a very high court of and for the unreserved category while attended within the all India rank of 160 for the SC category it only went up to 1500 to 1600 all India rank so you need to try to be within that top 1500 bracket of the all India ranks to easily get into the Maulana Azad medical College although I am talking about the all India quota admission is and for this your marks definitely has to be in excess of 600 to 620 but if you are trying to be late by as the Delhi State quota then maybe a marks in excess of 580 to 600 can get you into Maulana Azad medical College
Hope this helps,thank you
