Hello

If you are seeking admission in MBBS course, you should aim to score 550+ marks in the NEET exam for admission to government medical colleges. 200 marks are very less for admission. 

Also, admission to Government medical colleges is done on the basis of 15% AIQ and 85% state quota. Cutoff for admission under AIQ is very high. 
If you are seeking admission in any particular college, do let me know the college name so I can provide you the details accordingly.

Good Luck!
