Hi Brian! I personally use both notebooks and an iPad for school. The iPad is fantastic because I don’t have to carry a ton of binders, colored pens, or stationary around for my classes. Plus, if I make a mistake while drawing anatomy, I can just hit undo rather than finding an eraser and erasing. I would recommend getting a paper-imitating screen protector, because personally the feeling of writing on glass put me off at first.
I would recommend looking into an iPad Air, which I believe is a lot cheaper. Also, using your .edu email for a student discount, and maybe buying second-hand if that is a possibility.
I carry a notebook as well because some classes at my university don’t allow electronics. Hope this helps!
