Thank you.

See in compare to new IIT, IIIT Hyderabad is much more better and there is no comparison. But if you compare with top 3-4 IITs they are good in comparison to IIIT Hyderabad. IIIT Hyderabad is known for good placement in CSE. IIT also have good placement as well. I don't have any idea about curriculum.

You can get NIT, IIIT, GFTI. Your rank is good and you can get good colleges.

No, there are no chances of your because you has PCB in class 12th.

Biotechnology and M.Sc+Ph.D dual degree in Biotechnology, candidates must have passed mathematics at the (10+2) level. Bachelor's degree with Chemistry for three years or six semesters and Mathematics at the (10+2) level. Bachelor's degree with Mathematics for at least two years or four semesters.
