<p>I applied ED to Columbia and the results come out on Dec 15. I was thinking about applying to all my other schools if I don't get into Columbia on Dec 16. My question is, is there anything wrong with this? Would it be too late? Anyone done this?</p>
<p>If your other schools are RD schools with a deadline of late December/January-Febuary, then no, I certainly don't think it's too late. As long as it's before their deadline, you're fine.</p>
<p>As for working on apps, I would start that as soon as you would've had you not applied ED (for dec. schools now, for jan. schools in early december). That way, you're putting some good work into apps that there's a chance you'll need, and, even better, doing the apps for other schools will take your mind off the agonizing wait for Columbia's answer.</p>
<p>And if it turns out you did some work for nothing, who cares? You just got in to Columbia!</p>
<p>I would finish your apps now and then just have them ready to submit if you dont get ED</p>
