what is the minimum marks we need in neet to get a medical college for an obc student

There is hardly any difference at UG level in the marks needed by an obc n general candidate to secure a college . Obc category ka advantage tumhe unhi colleges mein milega jo central govt k funded h like bhu n colleges in south (this i m talking about neet UG exam- for the college u will get through all india ranking ) . For this you have to score a minimum of 500 marks to get a govt college . Scoring anything less than this will reduce your chances n in my view you will not get a college below 495 . So to b on d safer side , aim to get at least 500 .
This i was telling about college through all india ranking .

As far as getting a college through state ranking is considered,  there you'll get the benefit of your Obc category . But the cut off is different for different states n depends on the state you belong to .

Thx n all the best

Above 450 for better college
