<p>I have the book and it's SO HARD!!!!!!! Can someone tell me if it really works or if I'm just wasting my time.</p>
<p>The tips are good. The practice tests help you get become better at math, but do not help in preparation with the SAT. The practice tests, like Barron’s, are totally unrealistic. In addition, they require reasoning that is not tested on the SAT. I’ve heard that Gruber’s is the best when it comes to SAT math, so you might want to take a look at that if you’ve run out of Collegeboard practice tests.</p>
