This is more a Github related question, because Github gives away the Studentpack.
You only need YOUR OWN university email. So not the one of the university, but your personal one. Normaly you should get your own when you study. If you register for the Studentpack, you have to sign in with that email (or add it to the emails your is using). You get a link to the email to prove that it’s yours. After that you just need to tell them for what you will use the pack.
I’m studying Math and IT in germany and i guess i will be able to get this pack too. Though i’m still waiting for it since a month. Just try it. I don’t think it will fail (:
