The reason why I used my personal email address in the first place is because I thought it was gonna create a new JetBrains account for me under the email I wrote on the form when I submit it. I would like to keep on using my personal email address for my JetBrains account (for consistency), while keeping the license under my school email address (which is the part where it asked me to put my school email on the form). After I submitted the form, it redirected me to link my existing JetBrains account or create a new one so my license can sit there. It somehow still accepted it, even thought it shouldn't have.

Then, I went to the form ( ) to apply for a JetBrains student subscription, authorized by GitHub account, and entered my personal email address even when it specifically mentioned to enter my school email address, which I shouldn't have. The way I did it is I applied for a GitHub Student Developer Pack in my personal account by adding my school email address as a secondary email address.
