Our ds did some of the geometry stuff a couple years back and the instructions were lacking as to how to answer things, that I do recall.
I signed him up for the epgy algebra course and he liked it, did well with it, really well, although I did let him peter out at the end since summer had hit full-stride.
The explanations there were perfect, but I think that is a lot easier to convey than geometry!
I would absolutely recommend the beginning algebra course, however someone here did note it is a bit incomplete -- not really a solid substitute for a full algebra course. I do think it has given him insight to his own abilities and that is what I was hoping for.
