Pens and Notebooks!
Great stationery doesn't equate to better studying, but it can help! Here are John's favorites (as seen in class).
A favorite among our students: Pilot Frixion Pens
They erase perfectly and are great for note taking. Just don't leave them out on the dashboard of your car since the ink becomes transparent when sufficient heat is applied. [Worst case scenario: stick them in your fridge and your notes should come back!]
These are high quality pencils with soft lead (2B). Great for notes or general drawing & shading.
