Hi

If we are particularly talking about medical research, then btech biotechnological has more scope. Biotechnology is basically a research based course itself. You get many work opportunities in this field and also there's demand for biotech researchers.

On the other hand, biomedical science is also a good subject but has scope only when you go for higher studies and will prove good when you choose the clinical field. B pharma and biomedical science somewhat has similar scope and work opportunities are also limited.

Thanks
