I just got upgraded to a free github micro plan using my university email address. I'm planning to use the private repositories for some class projects this semester, but I'm wondering what will happen to those repositories at the end of 2 years when my free student upgrade expires. I'm assuming it's the same thing that happens when you downgrade from a micro to a free account.
Will my repositories disappear, become public, or just become read-only? I've searched around a bit and haven't been able to find an answer.
