My friend and I have been using this for years. My friend took it pretty serious this year:

It's really useful for courses in college, especially Language, Biology, Chemistry, and Physics for definitions, pronunciations, systems, etc.

Math and Computer Science is a bit hard since a lot of that requires practice and it takes time to figure out how to structure those cards.

Anyways, highly recommend them.
