Hello Shivangi,
Admissions to 12th are not controlled by state but eligibility is decided by the university. For B.Sc in biotechnology, bio is desirable but not mandatory in 12th.

Obviously B.Tech in mechanical or CSE or ECE.

HI Kev,
For the exam TS EAMCET 2016: For engineering stream a total of 1,44,510 registered for the exam.
We have 86000 seats this year in TS colleges. Qualifying rank for students is 91000.
So its very tough to get into.
& Few people may jump to other private colleges like VIT, Amrita, SRM, Manipal, IITs, NITs, etc. So, I hope you get in the remaining seats.
Please follow this link, that deals with the TSEAMCET college estimator(Mock Counselling) for a rough idea:

All the best.

Please be more specific, your state, board, etc.
