Hello,

You haven't mentioned any entrance examination

Though on the basis of your profile i suppose you are talking about EAMCET if not please specify.

The cutoff for all students is based on AP EAMCET ranks, therefore I'll attach a link for college predictor as well as a page where you can check the cutoff of each branch of those colleges there so you can have an idea of what the opening and closing rank of different institutions for Biotechnology will be.

You can check these links to clear your doubts about your chances of getting the branches.

I hope this helps.
