I agree that Alex would be good for filling holes. We did it over the summer to prep for 2 grade math skip. DD liked it a lot but I didn't feel like it was complex enough. For us, this might have been that dd should have been placed higher but I wanted her working at the level should would be doing in school this year. If we went back to it, I don't know what level I would put her in. I did love with Alex that DD could do it all independantly. I don't know how it would be for EPGY, but we may find out next year.
