Hello Anurag

If you take up admission in MBBS, you will need to cancel your previous admission in B.SC and submit all the documents in the medical college. Domicile requirements in MBBS vary from state to state. For eg in Delhi you need class 11th and 12th certificate from the state, in West Bengal you just need birth certificate and a residence of some time.

So kindly research about the same in detail. Apart from this, you need all your 10th and 12th documents, category related documents and identity proofs.

Hope this helps. Goodluck!
