What's the hardest sat book?

<p>I finished the blue book and the online course. I took the SAT twice and my breakdown was:</p>

<p>1st time:
Math: 760
Reading:630
Writing:680</p>

<p>2nd time:
Math:740
Reading:640
Writing:750</p>

<p>I want to increase my scores especially my reading, so SAT books have the hardest practice tests? I finished the SAT blue book and the online course.</p>

<p>Usually Barron’s is considered the hardest. Dr. Chung’s math is definitely one of the harder math books I’ve tried, if you are aiming for 770+ on math. CR really, if you are getting low 600’s, you most likely need to brush up your vocab more so than passage questions. Get word smart 1 and 2, memorize both and you should do well</p>
