<p>What is:
1. The best SAT guide (w/ or w/o actual tests)
2. The best ACT guide (w/ or w/o actual tests)
3. The best SAT subject test guides for US History, Chemistry, Physics, Math lvl 1+2, and Biology</p>
<p>The guides can be section specific i.e. best for crit reading. All and all I am looking for the best combination of books to provide me with the best strategy and the best practice tests for these tests. </p>
<p>I already have the blue book, official SAT subject Test guide, Princeton Review "11 practice", barrons for Chemistry. Are these all valid (especially the Princeton Review)?</p>
