Yes, biology students can appear for the CG PET exam, but their eligibility depends on the course they wish to pursue. If you have completed your 10+2 with Biology as a subject and Physics along with Chemistry (and possibly a vocational subject), you can apply for B.Tech in Biotechnology through CG PET.

However, if you are interested in other engineering courses like Mechanical Engineering, Computer Science, Civil Engineering, etc., you would need to have Mathematics as a subject in your 10+2. So, biology students without Maths are not eligible for these other courses.

In summary:

Eligible for: B.Tech in Biotechnology (if you have Biology, Physics, and Chemistry).

Not eligible for: Other B.Tech courses (require Mathematics i

n 10+2).
