You know they curved some for the Chem 111 lab, right? The final was ridiculous (which I failed) and was the worst grade I have gotten so far here. I initially got a B (87.5ish), but in the end, it shows on howdy (grades came out today) that I got an A! So you might not have to use anything if they curved well for you! I was so happy because that class was my only worry b/c of the B, but now it's starting off my freshmen semester with a 4.0!!
