When I studied at the uni 5 years ago we only collaborated over Google Docs. I'd strongly recommend online collaboration over sending files back and forth. For most things I ran Linux, and booted into Windows when there was a particular need for it, which wasn't often. But it all depends on what software you're expected to run during your studies. If you have room on your drive maybe having a minimal Windows install along side Linux could be a good thing?
Also, I'd recommend a distro that comes out of the box with working BTRFS snapshots. The last thing you want is have the machine you rely on for school shit the bed due to a bad update or something you do, and you have to learn how to repair Linux in the middle of an assignment that's due tomorrow. With snapshots you can just roll back to before it shat the bed.
