(bolding mine, which I disagree with a little bit)
I didn't read the book. I took the practice tests and if I didn't know a question, I would refer to the book for the answer. There are 10 practice tests, which I went through about 3-4 times. Many of the facts presented in the questions were similar enough to the ones on the test that it did help with the learning of the material.
Fair enough. What I was trying to address is the approach where people try to learn all the questions and their answers by rote, and that would not be a good strategy.
(And people who've not had North-American history, politics, and geography as the focus during their school years may benefit from some of the background/context the book offers)
