The cutof marks for the Tirunelveli medical college were 441 itseld for the unreserved category candidate in NEET. So you can expec the increase in the cutoff marks by 30-40% as compared to the previous year. In the second round you can try for the college mentioned above as you are on the edge of the cutoff marks so nothing can be accurately predicted for the second round of counselling. If the seats are vacant after the first round then you will be able to get the seat in the second round. So go for the counselling and try your luck. All the best.
