Greetings,

Most bachelor courses (except Law, medicine and a few more) have an age limit of 21 years for applying, there does not seem to be an age limit for this course however (only a minimum age of 17 years). Otherwise if you have a minimum of 60% in your 10+2 with Physics, chemistry, bio as your subjects then you are eligible.

here's some more info,

good luck!
