See
here for ALEKS's expectations about which courses get done in which years. They don't have a calculus course, which is odd. If you are boggling at the idea that US students take only algebra for a year and then only trigonometry in another year, etc., you're not alone :-) Part of the explanation seems to be that it's largely fiction, e.g. the "algebra" courses contain a lot of stuff that is by no stretch of the imagination algebra. I suppose the naming is "for historical reasons", but it isn't half silly.
