Yes if you belong to general category, then you need aporimiately 400-450 marks and above in NEET 2020 to get a good veterinary college. Also depends on the performance that year because the cutoffs change every year as they depend on various factors like number of candidates appearing and also the paper level, etc. And also depends on the state that you belong to. So try to score 450 and above to be on the safer side.

All the best. Thank you.
