<p>Of course it doesn’t guarantee anything on any single question. That said, over 12 years of full time prep teaching and thousands of students (including hundreds of CR 800 scorers), I have learned from experience (and copious data) that vocab memorization is the surest way to get big results fast. Nothing guarantees an 800, but no other method is as simple and foolproof as memorization. You don’t have to believe me (obviously, since you share neither my experiences nor my data), but my opinion on this isn’t half-baked or knee-jerk; in fact, I’ve come to this conclusion only grudgingly! After all, who wants “memorize vocab” to be an important part of a teenager’s vacation plan? Not this guy.</p>
