Hi, 

According to the cutoffs of last year you do have a fair chance of getting into a government college in bihar. 

Under 15% AIQ little difficult to get mbbs course, however theres a chanve of getting mbbs.

Last year patna dental college and hospital closed at 522 marks. 

You can have a better scope in the 85% state counselling. Althought you are in a tough spot for mbbs but still then theres a chance. 

Theres also the fact that the cutoffs vary every year and the trend keeps changing. Trend of this year shall determine if u get a seat or not.
