I am getting around 350 and I'm unreserved. what private college can I go to with the lowest cost ?

Dear candidate

At this marks there are very low chances to grab seat in private medical colleges at low prices. Mainly Karnataka and Kerala are two states where private colleges are low and found in the range between 6-9 lakhs/annum. Rather than this two states all have comparetively high fees than these two states. And at your marks you will not get get a seats in this two marks. You might get a private seat in uttar pradesh and bihar having fees range of 13-15 lakhs/Annum. As you belong to Assam so in my opinion prepare one more time and try to score in range of 500-550. You might grab a government seat in medical colleges there as Assam cut off for general are in this range only.
