<p>I've taken the SAT twice the first time in Jan with the scores of 550 CR/510 M/ 490 W
with no prep. I took again in May with the scores of 580 CR/530 M/550 W, not much prep, the Question of the Day and some reading up on Barron's SAT. I am really trying to get my scores into the upper 600s, maybe even low 700s</p>
<p>I have read the blue book and done a couple Collegeboard practice tests, but the math seems to stump me every time. I've worked on my writing skills and critical reading but I cannot seem to grasp the math skills. Can someone recommend a really good math prep book or course? Any recommendations for books or courses that will help with the other parts of the SAT is also welcome.</p>
