Hello,
If I consider previous years record, then a general category candidate must score least 532 marks to get mbbs in government medical colleges.
A SC category candidate require 380 marks and a ST candidate require 301 marks

Browse the link mentioned below, to check the colleges you can get.

This is just a prediction based on previous years records.The cut off  vary every year depending upon the difficulty level of question paper and availability of seats.

Hope this helps,
Regards!
