Hello

It keeps on changing every year, it mainly depends on the total number of repeaters and the total number of fresh candidates in that particular year. But for instance i would tell that the minimum marks you require is around 120 - 130 out of 180 and since you are a general merit student so you have to get atleast 125 .

If you get a rank of around 1.7 k -1.8k , you are sure to get a seat in BVSc. So, considering that you have scored around 94–95% in puc, a 140+ in kcet should be a very safe score.

All the best!

Hope this answer helps you.
