go through the indian thread, you’ll find many.
somewhere, i found that a chineese with 1700ish got in. She had a “desperate” story though. And I have known many students taking full IB course and doing very good: 2/3/4 below perfect score out of 45, get in with 1800ish sat scores into Mit, stanford and so on. may be even harvard.
i second that, with only 20 days of practice i increased CR scores by 70. Thats not great but many have got more and its all about practice with right material. There is no such thing as pattern of thinking. Truely, collegeboard says that even american highschool students have never learned CR skills.</p>
