It's a bunch of esoteric stuff, organic chemistry. Lots of rules about what's an yne and an ene and an ane, and how many double bonds there are, and what something is called, and which name goes first. I'm actually looking forward to it. I like esoteric stuff. It's part of the reason I want to go into medicine... which is probably one of the weirder reasons, but everyone gets to be a unique snowflake, so there.
Anyways, I'm two weeks away from finishing up gen chem 2, and from starting bio 2. Things are progressing. Until then, I'm buried in my chem book hoping to absorb enough to get much better grades on the upcoming exams...
