We're really liking EPGY too. I also wondered how it compared to since DS has progressed from the K stuff to 2.6 already. He does 1 session a day for the most part and is loving the math races he has to do before each session (started at gr 2 lvl)

He only does the language arts about once a week. He doesn't like it as much but it starts at grade 2 and that seems about perfect since he's high 80s/low 90s on it.
