So everyone says to get the AMSCO book for apush. I noticed that there is a revised versions of it but upon closer inspection it appears that on amazon the revised version is published earlier and the one on the AMSCO site is published in 2006 and i think it is the second revised version. Does anyone know if that’s true and if it is are all the answer keys out there the same for both? Did the revisions not affect the questions?
