<p>My kid is pretty self-motivated, so for test prep we went on line and bought previous edition test prep books from the College Board and a couple other test prep companies (read reviews for the ones that best covered our kid’s weaker areas). Also check out Silverturtle’s Guide here on CC. Then, bought a $100 gift card to the local coffee shop because that’s where my kid studies best, and that was it. Time also helped. His math SAT went up 90 points from winter to spring simply because of stuff they covered in class in the interim.</p>
