Hello Student

As according to your marks which are 257, yes it a little difficult for this score  to get a gmc seat this year, being in SC Cataegory also, since this year the paper was easy and the cutoffs are going to be sky high and the assesment made by rank predictor is based on how your rank is gonna be according to the present competetion scenario but on considering previous year's results chances are less but there is another twist in the story that this year due to aiims and jipmer seats have increased so your luck might win over all the uncertinities .

But i request you to first check the cuttoffs of neet 2020 by this link:-

Thank You.
