It's a good idea to get used to using whatever flavour of Office you prefer (Microsoft, Libreoffice, Google Docs, etc.) as pretty much any course will require written submissions and it's much easier to make and send them through the computer rather than by hand and through the post. On that note, also make sure that you're familiar with sending emails and attaching files to them as this is how you will send things to be marked.
Beyond that it depends on your course. If you're taking Mathematics then using something like Libreoffice or Microsoft Mathematics could be helpful; if you're taking Computing then learning to use Scratch (very similar to SENSE) and/or common IDEs like Visual Studio would be helpful. In economics and business you will most likely get a lot of use out of spreadsheets, so practice those.
Note taking software might also be a good idea, as mentioned above. OneNote, Evernote, etc. all perform this function well. Even Notepad works well enough on a desktop although it lacks the ability to sync with other devices.
Good luck with your studies.
