Bachelors

NEET score is required for admission to MBBS and BDS courses. Biotechnology, B.Sc or B.Tech does not require NEET score. For admission to B.Sc course in government or private institutes you would require either your class 12th board marks or there could be separate examination for the same, depending on the university or college. For B.Tech in biotechnology you need JEE scorecard, for admission in government and (some private institutes).
Most private institutes, however, conduct a separate examination these days or (rarely) might even consider your 12th board result. UPTU or now known as APJ Abdul Kalam University conducts a separate exam for B.Tech in biotechnology and so does IP University.
