Hi Saransh

Yes, as you mentioned that you have secured 630 marks and have delhi 85% quota  but didn't mentioned your category ,I'm assuming that you are from general category.

still you have chances of getting a medical seat in Vardhaman Mahavir Medical College ,if we see last year's cutoff ,that was,640 marks for general category(this year there is increment of almost 4,500 mbbs seats).

I hope this information prove shelpful to you.

All the best
