Hi aspirant,

The cutoff marks change every year. It's depends upon number of students that appeared in examination, number of seats available in colleges, difficulties of question paper, reservation catagory, previous years cutoff trends, etc.

According to previous years cutoff,  you need to score at least 450 to 400 plus marks to take a government bams seat if you belong to general catagory.

You can use neet college predictor to know which college you may get with your marks. That is mentioned below:-
