<p>Hi guys, I found these books called Barron's World History the Easy Way Volume One and Two on internet and I was wondering if I could use these books to prepare for the test. These books were published in 1997 and it's pretty old to be used as study guides for the SAT. And the reviews of these books claimed that these books have some grammatical, word choices problems and some chapters were not sufficient in sources. But they suggested to use these books as additional study guides along with the core prep book. I want to know if it's a good plan to use these books along with the core books such as Kaplan. I also want to know if these books are talking about the same time periods that the questions are asking on the test. If you know any good prep book for SAT World History, please recommend! Thank you. </p>
