Dear Kiara, different Institutions have different eligibility criteria for their Master's programmes. Neverthless, it totally depends on the Institution that you want to pursue your Masters from. On a general note, by pursuing Bio Physics in your Bachelor's degree, you are eligible to pursue M.Sc in Astrophysics. The minimum aggregate should be 50%. Few Institutions conduct admissions based on Entrance Examinatioms and few Institutions conduct admissions based on merit in your Bachelor's degree.
