Our teachers check our covers before an exam so this is not useful for me... anways the one of the friend it's the one that i could do XD good guide anyways
This is highly dangerous. I used to write everything that I needed on my legs. If you are a professional like me you can lift your shorts a little bit so you can read your infos and if a teacher comes to you and asks you whats on your leg you can just ask him if he wants to sexually harass you.
Very good guide. It has lots of details plus tons of pictures. I never thought about putting some formulas and things like that on the back of my calculator cover. 5/5
