caycecronk – yes, that happened w/my son too. We just moved really quickly through the first bit of lessons. was worth it for us to stay in A I think, but if you think he needs to move on you really could move up to B pretty easily. I don’t think you/he would miss a whole lot. I’m starting A with my younger son, who just turned 5, but its a good fit for him since he’s so young and has no math experience. He doesn’t even write well, which my older son did when he was at this age. Just a perspective – hope it helps. 🙂
