College Algebra Test 2

I hate taking tests. For some reason I tend to freeze up during tests, especially math tests, even after I studied my ass off. Take my last test in College Algebra, for example. I know the material back and forth, but during the test nerves take over. As a result, I made some stupid mistakes on a few problems. They were very minor, true, (I still got an A on the test) but it was enough to make me a little disgusted with myself. I guess the key is just to slow down and take my time as much as possible...and just relax.
