I m from pnjb.i got 508 in neet.can i do bams in delhi govt clg.if yes then how and when

First of all congratulation for scoring such good marks in neet. Yes you can surely get admission into delhi colleges by the help of neet counseling although there's very less quota for other state students in Delhi colleges hence the cutoffs are way higher as compared to local students but as you have a very good score you don't need to worry much about that.
Good Luck
