Hello,

If u want to avail a seat in the government medical college in Bihar in OBC category, then you need to score minimum of 450 - 480 in the 85% quota of state and 550+ for 15% all India quota seat. This range may change from year to year but from the past 3 - 4 the range is kinda same. This also depends on the type of questions that are there subjectwise and changes accordingly. So guys, study and get selected.

if you are talking about NEET UG examination then in order to get a government medical college seat availing the OBC quota in Bihar you definitely need to score in excess of 480 the  85% state quota and definitely in exercise 530 to 550 if you want to get a government medical college by 15% all India quota

but remember that this is subject to variation upon the performance of the different candidates and may change accordingly
