Hi aspirant,

You have not mentioned your state. So as from your profile you belong to Maharashtra.

With 243 marks in neet, you have no chance to get bams seat in government medical college . You need to score 460 to 480 Plus marks to take a government bams seat if you belong to general catagory.

This information is based on previous years cutoff and 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, etc. And this year cutoff goes very high. So more information you can use neet college predictor to know which college you may get with your marks. That is mentioned below:-
