<p>if i apply Early decision and get rejected by my top choice college lets say Columbia, can i apply for RD as well? does that go for all colleges?</p>
<p>Nope. If you're rejected from ED/EA, you may not apply again in the same year. Some schools have deferrals, where they'll review your app again in the RD pool.</p>
<p>I think most schools will simply defer you to RD, and if they flat-out reject you ED you probably aren't competitive enough to get in RD anyways</p>
