hi Prajwal,

I think you made some mistake because college of engineering in trivandrum offers only :

M.E /M.Tech., B.E /B.Tech, Ph.D, M.Arch, M.B.A, B.Arch, M.C.A., M.Plan.

There is no B.Sc agriculture course in college of engineering trivandrum.

However, there exist a College of Agriculture, Vellayani, in  Thiruvananthapuram  under Kerala Agricultural University which offers B.Sc agriculture course which is a 4 year course. And to be eligible you only need to pass 12th class and you should have science stream.

I hope this answer will help!!
All the best for the future!!
