<p>I am taking the SAT again in November. I have not been able to score above 650. Does anyone have any good online free resources where I can review concepts? Any basic tips? I seem to make stupid mistakes every time! I already have 2 practice books, but neither of them explain the concepts well. Thank you so much! Any response is greatly appreciated! </p>
<p>Have you looked at the Khan Academy videos? There is a section for SAT practice which goes problem by problem for the math from a released SAT. Also any of the videos in the sections of which you notice you have trouble. He explains things soooo well. Helped my daughter bunches.</p>
