Hi aspirant. The cut off for NEET 2021 for colleges has not been released yet as counselling is yet to start for All India Quota as well as in some states. GMC Mumbai has 85% medical seats for state counselling which are reserved under state level, regional areas and other reservation with various categories. As you haven’t mentioned your category, I’m assuming you belong to the General category. You must score above 650+ to get Grant Medical College or any other good government college in Maharashtra. Hope it helps!
