Which book is better?

<p>Is Barron's SAT math workbook better to improve Math score or is Gruber's SAT guide better?</p>

<p>Or do I solve both? Is Gruber's worth the buy?</p>

<p>Please help!</p>

<p>Gruber’s SAT by far.</p>

<p>Gruber is for 000-650
650-and up, I suggest Dr.Chung’s math workbook.</p>
