Test Preparation SAT Preparation

<p>I am scoring around 670-720s.
I cant decide on which workbook is more suitable for me.</p>

<p>Also, the PR rocket review is 90 dollars on amazon. Is there a cheaper way of getting it?</p>

<p>Thanks!</p>

<p>Im taking the sat January, is it good idea to get both prep books? (for 670-720s)
I feel like it could be too time consuming… what you you guys think…</p>
