Hi

It's quite difficult to predict that whether you will get  seat or not as  cut off marks/rank for medical colleges keeps changing every year  depending upon various factors like  number of students that appeared in the exam, kind of marks obtained by them , toughness level of the examination etc.

But yes dear aspirant,
When we go through  past year cut off data,  then with 251 marks, even though you are from obc, your chances of getting a seat in government medical college is very low

With your 251 marks being from obc, you might  get a seat in private medical college and deemed universities for which you can check your chances at

Thankyou
