I have to take a proficency test and I have to score in a range that would put me at the beginning of pre-calculus, or proficent in college algebra, geometry and maybe trig.
Can anyone suggest any review sites or tutoring sites to refresh me and get me up to snuff? I would prefer them to be free, and if not free, not very expensive. Or software that isn't for little kids?
Or any other general tips on cramming for something you haven't done in years are welcomed too.
