My son got excited when he saw this advertised. He likes reading them (Young Exp. Series) on his own and will do the same with this one. He’s starting Ap. Gen. Science next year for 7th.
He marinates in them; absorbing the material like a leech. HIs personal exposure to it should help him when he gets to the “big boy” Chem. and Physics books in a few years.
I also saw on Jeannie’s site that all the books will be on audio within the next two years, with Anatomy already available.
