Hey Arnab

Well it depends on the college and the seat pool you are getting the seat through. If you are getting a government quota seat in private college, then you could go for second round. But if you have got this seat through management quota, then you need to contact the college authorities regarding this, as admission for management quota is not through NEET counselling. It would depend on the college whether they allow you to do the same.

I hope this helps. Feel free to ask any other queries.
