Dolphin's getting 'credit' for the previous courses only in the fact that she doesn't have to repeat them. Or more, if she does it. Later she did it herself. It was really kind of nice, encouraged the speed without pushing too hard. We never got one that included division, but I believe there is one - our use of EPGY was broken up over several years, which didn't help.
