hi,

see admission to b.sc in biotechnology is based on score in 12th course or entrance test by respective university or institute. . the eligibility criteria for biotechnology course is candidates must have completed 12th course with physics, chemistry and biology/ mathematics as a mandatory subjects. however at this score it would be difficult to get any tier 1 institute based on 12th grade.

however apply for as many as colleges possible, I suggest you to apply for other stream like b.sc in life science or zoology/ microbiology as well to make best outcome of admission process. you may study m.sc in biotechnology after completing b.sc in microbiology/ biotechnology/ chemistry/ zoology etc.
