Just aced a test that I thought i did quite well on. I'd been doubting my self-evaluations for a while now so it was nice for a few reasons to see accuracy.
Turns out I should be able to get an A in the average math class at my level (this is stat400 but I think it holds.) by showing up, doing homework, and a little bit of book reading and studying. Why didn't people tell me this? ;)
