I love testing of any kind, and I think I'm pretty good at it.

As for as timed exams go, I don't let the pressure bother me. I speed up a little bit, but otherwise, I'd rather be almost positive that 80% of the questions are right than put a half-hearted attempt into all of them.

The only tests that have ever gotten me nervous are a couple Algebra II tests, and the ACT, the latter being the only one that was timed.
