Hello dear student, 

It's really difficult for you to get admission in any government medical college in Bihar and even in government dental colleges. I hope you understand that the cut offs are getting really high and it is really difficult for you to get admission even with the category while if you want to take admission in MBBS or BDS you can surely try under private colleges which comes under NEET . But for your reference I am attaching a link of the cut offs of the government medical colleges. Kindly check
