<p>I need a math prep book that teaches me how to solve a problem and its concepts. Like for geometry, I need detailed explanations that explain why it’s solved that way. Not just the usual this-is-how-you-solve-it explanation.</p>
<p>Suggestions?</p>
<p>Thanks!</p>
<p>Oh, and if I took the SAT bio test as a sophomore, will it be counted for college or do I have to take it again next year?</p>
