Depends on what course you are in rn, I think just a regular ipad air/any non-pro ipad (that supports apple pencil and buy keyboard folio. Accessories for iPad pro is pretty expensive, even w/student discount.

Non-pro ipad is good enough for apps like good notes, pdf expert (basically any notes taking app)

And do you really need 12.9”? If you are bringing it around campus in the future, 12.9” is pretty heavy.
