How ludicrous would it be to learn how Unity works without being able to use it? On the weekdays, I spend almost all day at school. But they don't have any kind of unity at school of course.Since you already know programming, not that hard. You could definitely get a hang of how the scripting works at the very least.
Do you know about general game dev concepts from Lumberyard? That'd also help. Update() vs FixedUpdate() for example are just functions that are called either every frame or every n milliseconds.
Newer versions of Unity are trying to be more dev friendly and have pre-built methods of doing most things and learning those would really benefit from having access to Unity, but most of the time I use my own scripts for things.
Have you tried installing Unity on a flash drive? You could then use it at school without installing anything on their computers.
