You thought your tests were hard? Our AP-Calc class nearly everyone scored Ds or lower, the only people that got above were people who scored 35 and 36s on the ACTs (basically one person), but I didn't study, because I felt the need to stick it to the man in every way. The only reason anyone survived that class was because of the completion based homework, I kid you not... I got Calc, but it never made sense till the next chapter started, so I ended up with a D the first semester, and then the second semester, EVERYTHING made sense, and I made a B, then I made a 4 on the AP Calc AB exam. I almost made a A in a pretty hard Calc 2 class, 10 points away... Calc is now a piece of cake, like regular math...
