Hello. I have registered to take the 2016-2017 AP US history exam as well as the AP European history exam, and I was wondering which review book would be the best for studying during the school year and for the exam. Currently I am leaning towards AMSCO for Apush, however I'm not sure if the 2016 edition is suitable for the exam in May of 2017. Perhaps you could give me some insight. I was also wondering about the Barron's review book for AP European History. Will the Barron's 8th edition work for the 2017 exam?
