Well, DS was already about 1/3 of the way through TT's Algebra I course when we switched to Aleks. When he first took the Aleks Algebra I placement test, it said he already knew a little less than a third of their Alg I topics. And now, according to Aleks' handy-dandy bar graph, DS is about 2/3 of the way through that list of Algebra I topics (after using Aleks for 6 weeks).

His pace seems too fast to me - for him to be able to complete Algebra I in less than 5 months at 8 years old. The fact that he is moving so quickly could either be the whole PG-pacing thing, or (my fear) that Aleks isn't rigorous enough. Again, math not being my strong suit, I'm not sure which option is the right one. I just want to feel comfortable with the curriculum we're using, and haven't heard from anyone using Aleks full-time for high school math...
