Hello Rutvik,

Ofcourse, there is a fair chance of getting management quota seats at a score of 250.

Keeping in mind the last year's cut off, which was a score of 134 out of 720, any student who scored above  this was considered as NEET qualified. And, all the NEET qualified students are eligible for 15% All India Quota and 85% state quota counselling.

You can check your chances of getting expected colleges on the basis of your NEET score by using our college predictor tool.
