Can't Access Github Education Domain on Namecheap?

I’m trying to claim my free .me domain on namecheap that comes with the education pack, but when I go to their education page - nc.me - and enter my primary github email to claim it, it says my email is not from a valid university. I’m in high school, so I’m not able to switch my primary email to my university email.

"If you are a part of the GitHub student program please use your primary GitHub email on the checkout form, instead of your student email address. " Am I in the wrong place? Thanks!
