I got 454 marks in neet 2020 belong to BC b female will I get medical seat in andhrapradesh?

Hello mam, your marks are enough to get you a college but it depends if you want a government college then there's very low possibility that this can help but if you are looking for private then yes you can get a seat all you have to do is register as per state counselling also you should be sure about the college in which you should apply for that I recommend you college predictor.

Also, you haven't mentioned if your domicile is of andra pradesh or not because it is not an open state and doesn't allow students of other states in their state counselling. But to help you with all details I'm giving you a link below of list of colleges in AP and every thing related I hope this helps.
