Post-Test Terrors

Oh my, hardest test ever. I've never seen a test where so many people in my class, way over the majority of the class, not finish, many of the people weren't even close. In hindsight I should have have studied a little bit more, especially my polyatomic ions. I ended up forgetting what the formula for bicarbonate was, and was unsure on a few others, probably should have done this a couple of times before hand. I also missed an easy question because I thought 6.02 x 10^23 was Mendell's constant and not Avogadro Number so that stinks. Ended up guessing on like 7 questions, but was happy she gave an free one (just told us which one to circle).
