Barron, PR, Kaplan or CB?

<p>Hey guys, I am taking SAT II Chemistry, Physics and Math II. Which of the mentioned books should I get? I would want the ones that are the most rigorous. Thanks!</p>

<p>If you want rigorous, go for Barrons. If you want realistic, go for CB or Princeton.</p>

<p>does CB have a particular book for chem?</p>

<p>and where can I buy some tests, i heard that CB has just published a book with all SAT II tests? so how many tests does it have for each subject? i don't want to buy a whole book just for one or two tests</p>

<p>thanks in advance</p>
