<p>I have read all the stickies, and I am very confused!</p>
<p>There are about 5 editions of the Gruber books, and I am looking for the one that will help move a 680-710 math score up to 760-800</p>
<p>I am particularly interested in getting the last 2 questions right in the section, especially those focused on 3D geometry figures and abstract functions in coordinate planes. Do I need just the math workbook? The 2009 complete guide? The 2010 complete guide? The "2400" version?</p>
<p>Has anyone else been in the 650 range and struggled with the toughest questions, only to study with one of these Gruber guides and end up with a 750+?</p>
