B.Tech Biotechnology

B.Tech Biotechnology Vs BSc Biotechnology:
B.Tech degree in biotechnology encompasses both the biological sciences as well as the engineering aspect of biotechnology. The B.Tech curriculum will cover life sciences subjects such as microbiology, molecular biology, genetics, cell biology, etc. and engineering subjects like bioprocess engineering, biochemical engineering, thermodynamics, mass transfer, etc.
A B.Sc degree on the other hand focuses more on the biological sciences aspect of Biotechnology. Yes, there will be a few subjects (1 or 2) related to industrial processes but the main emphasis will be on R&D in biological sciences fields such as Biochemistry, Plant and Animal Biotechnology, Microbiology, Molecular Biology and Microbial Genetics, to name a few.
There is no such thing as B.Tech being better than B.Sc or vice versa. Students must choose a course that aligns with their long term goals. Do you want to pursue a research career in areas such as Stem Cells, Genetic Engineering, Plant Biotechnology, Molecular Biology etc.? If yes, choose B.Sc/M.Sc Biotechnology or BSc Biotechnology and MSc in any specialized field of Biotechnology. You can later on pursue your PhD if interested.
If you want to keep your options open, then go for B.Tech Biotechnology. Many B.Tech students who do not find jobs in biotech sector shift to software, management etc. So, this is an added bonus for biotech students and this kind of transition will be tougher with a BSc and MSc degree in biotechnology.

Yes, VIT Bhopal does have biotech courses, but let me make one thing clear. this is newest campus of VIT, and last year, students got CSE below INR 1 lakh rank easily, and I think it is not better option to take admission in Bhopal campus, because fees structure is similar to VIT Vellore and Chennai campus somewhat. And, it's infrastructure is not fully completed, and still it is under development.

If you think to take admission in VIT, then you should refer Vellore or Chennai campus now, and if you are not getting this campus, then you should try other university or college.
