Yes, great review! DD has done some Alcumus and work with some of the AoPS books but it does make me wonder whether DD should ever take this course because I am not very mathy at all and it has been sooooo long since I had geometry. So it would take a significant amount of effort for me to even try to 'unstick' her, assuming I could even figure it out. Does AoPS have tutors available, or people you can ask if you get stuck with a problem and don't have a helpful parent or friend around? Otherwise I am not sure how DD would be able to deal with this course, as she is quite mathy but does get very frustrated when stuck, and I am of very little use despite my most earnest efforts. frown
