Hiii Kanika,

You will be happy to know that your score of 516 marks can fetch you Government Doon Medical College, according to last year cutoffs. As you have the state domicile of uttrakhand, it won't be difficult for you get this college. For unreserved categories, one can get government Doon Medical College if he/she scores 530+ in the 1st round of counseling and in the 2nd round scoring 510+ can easily get you this college. (If this year's cutoffs goes nearly same as last year )

I hope this answer will help.

All the best for your future!!
