Steps:
1 - A students card, can be yours or from a friend or relative, doesn't really care, you can even search for some real images on the internet and then give it a little photoshop. Make sure that the card has a photo, a name and a year (must be this year duh).
2 - A github account
Head over to https://education.github.com/pack and click on "Get the pack"
Login with your github account and then it is gonna ask you some questions, put that you're a student, put your normal email and then where it says "How do you plan to use GitHub" just write something like "I'm going to use github as a tool to host my projects and learn with other people"
Now, you see that they're asking for a picture, just add a picture of the card you got from a relative or photoshopped, as long as it fills all the criteria I said above you will be accepted. If you're using your own card you can just add your own picture.
And that's it, wait like 2 days (sometimes a couple hours) and you'll receive an email telling you that you got accepted (as long as you didn't fuckit up)
Now all you gotta do is to enjoy your free stuff
Btw you can actually do this multiple times you just gotta think with yo head
