• These notebooks. It works like a binder. You can take paper out, put new paper in and move stuff around as you see fit.
  
  
• To go with the notebook is this hole punch. With this you are also able to put in important documents that you use every lesson.
  
  
• These pens. They are erasable and have a very fine tip so they are ideal for drawing diagrams and writing super small.
