<p>Ok for ACT you have, in my opinion, the two most realistic/best books to use. </p>
<p>As for SAT, I might caution you against using Barrons. Barrons has rep for being much more difficult than the actual test, and having somewhat obscure test questions. However Barrons will comprehensively give you a review of the toughest questions you might see on the test. So in other words the prep section in the Barrons book will probably be very good, but the tests are kind of unrealistic/overly difficult.</p>
<p>SAT II’s wise, Barrons will prepare you for the toughest/worst case scenario test. If you’ve understand/know everything in the Barron’s book you will be fine (perhaps even overly-prepared for you test). In other words there is some unnecessary prep in Barron’s SAT II books, but it’s very comprehensive nonetheless. I might recommend checking out Sparknotes SAT II’s, because the they’re free and online, and are more realistic. Princeton Review is another good option.The Official Collegeboard Blue Book may have good tests, but there’s only one or two tests per subject, and the prep is very minimal.</p>
<p>There is a very comprehensive guide on the SAT Forum called Silverturtles guide… It gives recommendations for the SAT that are also very helpful for the PSAT. It has been well researched and many CCers are finding it very helpful.</p>
