generally speaking, macOS already comes with quite a few great tools for "learning"
didn't go to a university myself, but i'd guess that it'd be helpful in your case if you looked into the MS Office Suite (Word, Excel, Powerpoint, Outlook, Teams) and maybe Adobe Acrobat
Not that you couldn't basically use what already came pre-installed on macOS perfectly fine too, but compatibility issues might more or less require you to use some certain software that more or less are de facto standards in their fields.
But look into what your university actually expects you to use, before spending/investigating anything costy
