We recently switched from abeka math to Saxon and it was a great fit for us! My daughter was struggling with the fast pace of Abeka and not enough explanation and with Saxon she has been completely independent. We got the teaching DVD and the teacher explains the lesson so well! My daughter said that the teacher breaks it down in a way that she can really understand. We are very happy!
We were looking for a program that my 8th grader could basically on his own. He picks up things slow, and when we just had the book he tended to skip the instructions. He also loves to do anything on the computer. This is working very well for him. The instruction portion of each lesson takes usually 30 minutes, an goes through everything from the book, for him he needs that. It may be too drawn out for some kids (get bored), but works well for us. He is able to do math completely on his own (so far after 6 weeks of school).
