I currently use the MacBook that I had throughout undergrad and an iPad pro. If classes are going to continue to be offered remotely and in-person, I would definitely suggest having two devices (so that you can stream the lecture on one and take notes on the other). They have sent out a few warning emails about the exam software possibly not working with Mac updates but they also offer laptops for you to use to take the exams on if you run into any issues, with that being said my MacBook has worked perfectly for every exam so far! I just got my iPad at the beginning of this year and would absolutely recommend investing in one, the apple pencil is a must for notetaking and apps like Notability make it super easy to mark-up lecture powerpoints and virtual labs! Overall, I use my laptop for streaming lectures, Anki, and test-taking, and I use my iPad for note-taking, drawings, and virtual labs. I know lots of my classmates use different tech and everyone prefers something a bit different, but I would say that if you like your current devices there's no need to dump them!
