I wasn't really ready to take it the first time (freshman spring...), and dropped it before the halfway point so I wouldn't take the hit on my GPA. US colleges are all over the map with regards to how flexible they are about course order, and even between different degree programs at the same school. My alma mater had a somewhat weird trimester schedule and was relatively flexible about offering sections of courses year round - they had a bit of a housing shortage that made it impossible to house all the undergrads on campus at the same time.
