So, Questions and Melmichigan,
Your impression was that Aleks doesn't cover the material as well as might be needed, or that there wasn't enough review? I looked at it briefly, but have no experience.
I think it might be little of both. Then again it had became a major fight to get me DD to use it by the time I called it quits. I still have a few months left that my youngers are using for quicktables because the subscriptions are paid for but wouldn't be used otherwise (wish I'd never signed up for so long).
My DD will explain that she would "forget" how to do something from the time she was first shown it and did the problems correctly to when she was asked it on assessment. (I see they have added a quiz option that wasn't there when she was using it.)
My DD only scores low 140's in math from her testing two years ago. I had her go back and start at 4.5 with EPGY and review forward when we started it. She says she is remembering more with EPGY "definately".
(I asked these questions of her so you would get her view on the programs.) HTH
