I bought my ipad pro last semester specifically for school. It's great because I have my notes all in one place and I can look back at stuff from past semesters. It definitely would not be worth the money without the apple pencil but it is the best stylus ever and you don't have to worry about having your palm on the tablet because it has palm rejection technology. It's like writing with a normal pencil, or as close as I've ever seen.
I have the 9.5" pro because the 12" is just too big for me. If you are a note-typer I would recommend the logitech create keyboard case too. It's cheaper than the apple one and a lot nicer. Also has a little slot to hold your pencil and provides a lot of protection for your tablet.
I'm still in undergrad, but I definitely plan on using my pro in vet school.
