hi,

see since you dont have biology in 10+2 course, you are not eligible for mbbs or bds or veterinary or physiotherapy related course. now you may study bsc in different stream like, bsc in physics, / chemistry/ mathematics/ computer science. if you study computer science it will lead you to have two paths, you can join in teachig field, or do higher study and can do job as a computer engineer, so you have left with options in bsc in physics, chemistry or mathematics or you can go for commerce line or business development related course like bba or bms.

now the decision is yours, if you want to stay in science relayed field you can do bsc, if you are a maths lover you can apply for isi b.math course program, which has also a great career ahead.
