School account to personal?

Hi, does anyone know how to switch my account from a school account to a personal account? I signed in using Google, and my account defaulted to a school acount using my school email, but in order to use my student license to get the program I need, I have to register under a personal account. I can't figure out how to change, or even to delete the account connected with this email so I can start again. Does anyone know how to help?
