Reddit mentions of The Classics Reinforcements Stickers, for Punched Holes, White, 17 Sheets, 544 Count (TPG-462)

Ok, this is what got me through engineering undergrad:

• A zipper binder. Carry all your notebooks and writing utensils and a calculator.
  
  
• Similar to your notebook choice: Wirebound + 3-hole notebook so it goes in your zipper binder. One for each note-taking class.
  
  
• Binder 3-hole punch, if when you get handouts in class that you want to put in your notebooks chronologically, but hasn't been punched.
  
  
• Hole protectors. You'll need them. Trust me.
  
  
• 0.3mm lead is a lot easier to come by than 0.2mm. Get a good 0.3mm drafting pencil instead. Get a good eraser too - don't get used to using the shitting pencil-tip erasers. A bonus to using non-standard lead pencils - people are much less likely to bum lead off you.
  
  
• Scientific calculator. You really don't need a graphing calculator, in my experience. Anything beyond a Scientific calculator you can do it on Mathematica or MatLab or Maple or whatever your school provides on their computer labs. Look through this list and choose one, because you'll eventually use that on your FE/PE exams, and it's better to walk into those exams with 4 years of experience on your calculator already.
  
  
• Eventually you'll be printing out your résumé, and shitty computer paper isn't going to do it. Don't shell out for stupid "résumé paper", I have a whole rant about that and the paper industry's creation of fictitious product demands, but that's another story. Make your résumé professional, concise, and elegant (good résumé-writing is worth another lengthy discussion), and then print it out on some cardstock - a bit firmer, a bit more professional than crappy computer paper.
  
  All of this will probably fit in your cool zipper binder.
  
  This was kinda fun, actually.

I saw a picture where someone took these and painted them and put them on the top of each bottle.
