Found an old copy from 2015 on sale in the library. I was surprised about how much I did know and on the same token how much I didn't know. Mcgraw-Hill and I go back to the sixth grade, I read that world history text book from back to front 3 times. I have never failed history! With that in mind read the textbook a couple of times so the material is crystallized. (See what I did there!) I do however feel that some of the more unproven theories and modern speculation are left out. This however is good for the basic understanding, most of it seems common sense.
