I looked at a few high school courses descriptions for courses with that kind of name. They look like lower level introduction to precalculus and statistics for students who struggled with algebra 2.
Such courses would not be a good choice for the OP, who is doing well enough in precalculus and could probably do fine in AP statistics. That may allow the OP to go into college with the math or quantitative reasoning requirement fulfilled (depending on the college and AP score), instead of having to take such a course in college.
