Smart enough to cheat but not to study

If it’s a math test with calculators write the formulas in pencil on the calculator. Just get a black calculator. It’ll come off as soon as you wipe it and with a bit of liquid even faster.

I can think of like 20 easier ways.

Good cheating is learning. Creating a really helpful cheat sheet usually makes you remember stuff without looking at it.

I had a double sided A3 sheet with all the info I needed in my pocket during an exam. I was in a room all by myself and no teacher checked on me throughout the whole thing. I could have cheated but I didn't because it wasn't fair on the others.
