@roundandround : Use credit for intro. Take intermediate once you have college or AP credit for calculus 1. I don’t think econ. 101 and 112 are that helpful. They are large lectures that are not but so rigorous (just because something is a college course DOES NOT mean it goes more in depth than an AP/IB equivalent. It is largely professor and class size dependent. At many school I’ve seen, someone with AP credits in economics should not bother taking them in college).
