Dear candidate,

If 489 is you general state merit rank then you would get a government medical seat in Tamil nadu.But if it is your state category rank then looking at your AIR rank and the state category rank,There is very very less chance for government college.

You may get private college by state quota,there are fair chances.

ALL THE BEST FOR YOUR COUNSELLING!
