I aksed this same question on the WTM boards, and was told that Aleks isn't "spine" worthy (to be used as the main resource for a course) and that it wasn't rigorous.
So...now I am worried again. I am considering getting a standard Algebra textbook, like Houghton-Mifflin, to be sure that he's really getting the depth he needs. I know that if he doesn't have a very solid handle on Algebra that the other upper-level math courses will be very difficult for him. I feel like I need an educational advisor or something.
