I scored less then 50% in 12th boards can I get into private bsc biotechnology college

The minimum eligibility requirement for BSc. Biotech at an Indian college is having passed 10th and 12th with Physics, Biology/Maths and Chemistry as core subjects, and at least 50% overall (45% for SC, ST) and 60% in each of the core subjects in the 12th boards. Both PCM and PCB candidates can opt for BSc. Biotech.

Given that the eligibility criteria demands at least 50% in the 12th boards, it might not be possible for you to seek admission into BSc. Biotechnology at an Indian college.

But I would advise you to go through the eligibility criteria of some of the private colleges by visiting their official website.
