There is a tough chance to get a seat with the rank that you have mentioned above. However, if you are willing to take up management seat, do contact the hall of admissions.

The eligibility is 50 percent marks in B.Sc(Pass or Hons.) exam. of PU or other exam recognized by PU as equivalent thereto with Botany as one of the elective subjects.

Your score in NATA not so good but as your board marks are good so it may be possible to get seat in Reva. You have around 60% chance to get a seat.
