The sequence of importance are:

• btech biotechnology in srm university
• btech biotechnology in sathyabama university
• bsc+msc biotechnology in vellore institute of technology
• bsc biotechnology in amrita university
• bsc biotechnology in manipal university

These should be your priority list of choosing the course.

Always try to choose the BTech or BSc-MSc program because only BSc will not avail you to get a job (until and unless you are doing a 4 years BSc Research with good project work). So having a BTech increase your chance of getting recruited in the applied and manufacturing section as well as BSc-MSc will give you a chance to work in the Assitant Posts of R&D. Although it may vary from company to company.

I hope my answer helps. All the very best for your future endeavors!
