Raise my CR score

<p>Hello, I've been constantly getting in the low 2100's because my mid 600 CR score always brings me down. Is there a way to raise this score in a short amount of time? thanks</p>

<p>i used a CD from Kaplan. went from 610 to 680. used it a day before the test. but, it was pretty expensive. a few hundred dollars. lemme see if i can find a link to it.</p>
