B.Sc Agriculture is an undergraduate course and the required qualification to appear for entrance examination to get admission in the course is that candidate must have passed 12th from a recognised board.

Candidate must have passed 12th in Physics, Chemistry, Mathematics or Biology.

So, if you have not passed in Mathematics and have Biology as main paper then you are eligible to appear for entrance examination.
