If you are a PCB student then you can't apply in IITs and NITs if you want to pursue B.Tech in biotechnology. But many private universities are there that do not keep maths as a compulsion.
Some of the best universities are:
1. VIT, Vellore
2. Amity University, Noida
3. SRM University, Chennai
4. Jaypee Institute of Technology, Noida
All the best!

Any applied science brings faster placement than a pure science. So, go in for Bio-Technology.

Best of luck.

Biochemistry has more scope than bio analytics, but your interest and passion is more important.

B.Sc Micro and Bio chemistry courses are common and there are many colleges that offer these courses. But agricultural engineering is a rare branch , only few institutions conduct this course. So its more demanding course than Bio chemistry and Microbiology
Agricultural engineers have opportunities in agricultural research centers, universities , large scale nurseries, plantations etc.
