And I dont think they take admission on the basis of NEET marks but on the basis of your class 12th aggregate in which you have to score a minimum of 70% in pcb in from OC. It's based on +2 mark. While 15% ( VCI quota) is from NEET.  Go through the last year cutoff so that you will get an idea about admission (for OC it is around 190 out of 200in the total  of biology+ physicsand chemistry average)

Tamil Nadu Veterinary & Animal Sciences University (TANUVAS) offers around 250 to 300 seats every year for BVSc course
