Hello,

So, here each field has it's own advantages. If you go for Bsc Nursing it's totally a medical field, you need hard work here.

As for Bsc biotechnology, bsc biochemistry this fields are research oriented fields. If you go for biotechnology field it has vast career opportunities in future. I personally suggest for btech biotechnology as it's my path after completing graduation from biotechnology you even can go for biochemistry, microbiology, immunology as a speciality in your masters.

If you want to do bsc biochemistry, you need to fix your career path.. If you're confused between all biology related subject go for biotechnology.(btech-4 years, bsc-3 years)

Bsc Biochemistry is good choice you can do masters and phd and even can become a professor or can further study/research.

So, think carefully which subject you're interested in and choose wisely.
