Hello, 

526 is a good score. Looking at the last year's cut off marks as reference you have a good chance of admission in the following colleges.

1. Government Medical College, Haldwani.

2. Veer Chandra Singh Garhwali Institute of Medical Sciences and Research, Garhwal

3. Government Doon Medical College. 

You can also try for admission in Private Medical Colleges for MBBS courses. You have a good chance of admission in Uttarakhand state quota counselling with a score of 526.

Good Luck.
