Hello Aspirant,
Yes you can change your stream from B.Sc to B.Tech but you can do this only after clearing the required conditions and criteria for switching between the streams. You need to have maths as an compulsory subject in your 12th standard and you have to cancel your admission under B.Sc stream and apply for the B.Tech Biotechnology again with the demanded fee.
However, there will be some compensation taken by college when you withdraw your admission from B.Sc. Also you need to appear for the entrance if any taken by the college for admission into this course.
Hope this helps!
