<p>Been getting 31-33 ish on various practice test portions after reading this book. Good reviews too. It provides lots of strategies, which makes it really useful.</p>
<p>It has a pretty big math section that reviews things for basic geometry to trig to algebra etc. I found it to be a very good review.</p>
