Hello, 

A score of 611 is a very good score. If we look at the last year's cut off marks which are 620 and above for open category under All India Quota counselling in Delhi then the chances of admission are less. You can get admission for BDS courses in Delhi under All India Quota counselling.

If you are ready to study in other medical colleges that is in other states like Tamil Nadu, Maharashtra, Uttar Pradesh, etc. then I can suggest a few colleges for MBBS under All India Quota counselling

1. Grant Medical College, Mumbai

2. Stanley Medical College, Tamil Nadu.

3. King George Medical University, Lucknow

4. Lala Lajpat Rai Memorial Medical College

5. Lokmanya Tilak Municipal Medical College, Mumbai

6. Topiwala National Medical College, Mumbai.

You have very good chances of admission in these colleges under AIQ counselling. 

Good Luck.
