Notebook, paper, and a pen...that's all I take to class every day.
Laptops aren't necessary (they're distracting more than anything), and big binders (like the ones used in high school) are also not necessary because you don't receive many handouts.
So, buy a couple notepads (one for each class, or 1 for two classes), get a couple pads of paper, and a couple pens and you're set.
