See if you can access your university email account. They may have sent you emails.
See if you can access your degree program from the webpages... They may have put course outlines up that detail what you need. That will typically tell you the required / recommended text, at least. If there is one. Or the uni bookstore will know about compulsory / recommended textbooks.

You will probably find that most students will rock up to the first day of class with no clue what is going on. Usually... Most first year courses take the very first lecture to give you an outline and work you through it... So you know what books / manuals you need... Whether you need lab coats or goggles or graphing paper or whatever...

Different people have different preferences with respect to how much they like pen and paper and hardcopy books vs going paperless. Paperless can be cheaper if you can hunt out PDF's of textbooks (I'll say no more about this). I personally think that there is something kinesthetic about pen and paper (actually, I prefer nice mechanical pencils)... But it depends a bit on personal preference / what you are studying and the like.
