I actually bought the KBB before I thought I was going to take the online course. In all, it appears the "review notes" from the online course is pretty much the same, but the book for the online lecture has the PAT stuff with quizzes and a few extra mnemonics and info. Although, I can't say for sure since I only looked through the KBB to make sure I wouldn't miss anything besides the CD in the back before I sold it to a friend. If anyone knows differently, feel free to correct me.
