Hey there

You have good score but the cutoff has increased this year so at 12478 rank you have lesser chances of getting a government medical College in AIQ. As you have not mentioned your state so I have given information about AIQ in state quota you have chances of getting a government medical College. Though in AIQ you will get various dental colleges in states like Orissa, Rajasthan, telengana etc.

Dear candidate,
Colleges is totally depend on the marks you got and the rank. Different states have their own criteria for seats to allote. Under state quota the 85 percent reservation for state students and under all india quota the 15 seats for the other state students.

As you have not mentioned about any state, its difficult to say about any college with any information. Go for the home state seats there you have very much chance for the government medical college.

For that here I am providing you with the link of our site portal to predict your college by just mentioning your information for the college and know you applicable colleges.
