Hey

Every year the cutoff mark to be in the top 10000 ranks changes so it will be difficult to accurately say something. This year most cbse and isc students have got higher than usual marks too. Still I will help you with whatever I know.

You neet atleast 65%(according to previous year data) to be in the top 10000 ranks. For this you need to score a minimum of 65 out of 180 in kcet exam, however I will recommend you to give your best and try to get as much as you can. All the best.
