Moral based question:

[GTripp0012]

As someone who's already done this (on a TI-84 never-the-less), it's definitely cheating. With that said, it's not particularly helpful cheating. If you have to go to the formulas every few seconds, it's going to be tough to stay in a rhythm that is conducive to successful test taking.

In general, I prefer not to cheat because I treat grades as more of a way to see how apt I am/am not at certain lessons rather than a chance to show everything I know. If I feel I'm going into a situation where clearly, the test is just going to be an unmitigated disaster that's totally unhelpful to me, I'm not above doing something to show that I do understand what I'm supposed to.

From either perspective, I'd say you are making the right decision.
