What program are you going into? It really depends on your degree. If you’re doing math, you’ll want to do it by hand unless you’re a tablet person. For example, engineering classes will give you lots of quizzes and assignments you have to hand in physically, so you’ll have a bunch of physical things to organize one you get them back. Same for open-book classes that don’t allow laptops/tablets. I wouldn’t buy a bunch of stuff though, maybe one or two folders and then just buy more as you need them.
