Hi, 

Well if you are looking for a mbbs seat in delhi then its difficult. The cutoffs for the medical colleges even with delhi quota is very high.

Evem for other states under 15% AIQ its difficult to get a seat.

As for private colleges you can apply for private colleges in states like UP etc. You have a fair chance of getting a seat there.

You can also opt for deemed universities. Although the fee structure would be high but chances of getting a seat are also high.

I shall give below the link which can help you decide better:
