Head over there now and try it out (you get around 10 questions in any area free), but the real advantages are the heuristics (the computer adapts to your child’s abilities in each area of math) and the reporting (you get wonderful information about how many minutes, problems,  trouble spots, what’s been mastered, etc., complete with graphs. We targeted 25 Harley students who we thought would profit the most from this visual, computer-based, repetitive, heuristic style of practice, and it’s working great for those who are spending time on it.
