Hey student,

I hope you are doing well.

NO, there is no such rule that only girls can opt for B.Sc Life Science program (except if it's from an all girls institute, of course). Any one can take admission in B.Sc (Life Science).

You can visit the following link to check the colleges offering B.Sc in Life Science:
