<p>Erica Meltzer’s book “The Critical Reader” is good for RC. For math, there’s a ton. You probably know Khan Academy, right? Can’t go too wrong there: <a href=“SAT | Test prep | Khan Academy”>https://www.khanacademy.org/test-prep/sat</a> There’s good video explanations with math here: <a href=“http://www.satquantum.com/satpracticetest/”>http://www.satquantum.com/satpracticetest/</a></p>
<p>There’s a ton of books, but these are what come to mind. I accidentally landed on your post…sorry if these aren’t what you’re looking for. </p>
