"Avery and Levin, who studied the high school class of 2000, found that at the most highly ranked colleges — Harvard, Yale, Princeton, Stanford and MIT — the early admission pool tended to be better-qualified than the regular admission pool. But at colleges just below the very top, early applicants were actually less qualified, and they were still admitted at higher rates." from http://www.vox.com/2014/10/16/6982235/early-admissions-to-colleges-help-kids-who-dont-need-it
上面有统计说那五校的ED学生比RD学生强,其他学校反过来,ED学生比RD学生弱。正确做法很明显。如没有八分把握,ED其他学校. 或先EA其他学校,再RD这五校。
