Hi Naseem

You didn't mention the state, you hold the domicile of

But in general as per past year trends , if you are from OBC category and want to get a seat in a government medical college for mbbs then you should try to get at least around 580 marks to be on the safer side in your neet 2020 examination

For example,
In neet 2019 in UP , lowest marks required for obc category for getting a seat in government medical college under state quota was 573 and it was for
Medical College, Bahraich

Government medical colleges are quite cheap when it comes to fee structure ,thus they are very affordable , for example PMCH is a government medical college and its fee is only around Rs 27.90 k for the complete course of MBBS

Good luck for your neet examination, prepare well :-)

Thankyou
