Hi,

500 marks is a nice score. Your sister can really get a good government medical college. For your category, one need to score above 550+ marks to get into a government college. The safest mark is above 550. With a 500 score last year, she can definitely get a seat if she studies more for those extra 50 marks. Also try to complete all the counseling rounds for Telangana.

Hope that helps

All the best.
