No, you don't. You get a dry-erase board (actually it's two laminated sheets) which you can turn into a "formula sheet" by putting down during the computer instruction all the formulas you want and have memorized. It could be handy.
LOL!!! ROFL!!!
sorry, i am not laughing at you.
It's just so funny becuz everyone was so paranoid about memorizing all the formulas and this thread just made me feel empty 🙂
