it would be better if you had mentioned your state . getting a good private college with low fees is quite difficult .it also depends upon the courses you want to get in .however do not lose hope here i am providing a link so that you ca check it by yourself 

i found christian medical college a good option however look out for other colleges in your state

HELLO! RAJKUMAR

SOME PRIVATE COLLEGE LISTED BELOW:

(1) MS RAMAIAH MEDICAL COLLEGE.

(2) SRI AUROBINDO MEDICAL COLLEGE INDORE.

(3) JAWAHARLAL NEHRU MEDICAL COLLEGE.

(4) MAHARAJA AGRASEN MEDICAL COLLEGE.

(5) RAIPUR INSITUTE OF MEDICAL SCIENCE.

* LASTLY REMEMBER MEDICAL IS A PROFESSION WHERE YOU CAN EARN HUGE SO IF YOU CANT ABLE TO GET GOVT YOU HAVE TO SPENT SOME LITTLE TO ACHIEVE SOMETHING.

ALL THE BEST.
