Must haves for college?

So far on my list, I got:

Noise Cancelling Earmuffs/Headsets (studying)
Laptop
Bookbag or other bag
Organizer
TI-89

  • Rubbers
  • Deodorant, soap.
  • Bike
  • Printer + paper + ink.
  • External HD.
  • Tortillas.

What else should I get?** I’m not living on campus**. I’m thinking about a sound recorder to record lectures, not sure what people think about it though?
