<p>I thought you could only do either one EA or one ED.
I see some CCers that did one ED along with a number of EAs.
Single-choice means that you can only do one...
But "technically" it shouldn't matter.
I guess some CCers are just some of those dishonest nerds that cheat all the time. Hmm.</p>
<p>I think that is only bad if you are applying to a single-choice early action school. I'm not too knowledgeable in such matters, but there are two types of early action and only single-choice has such restrictions as you mentioned. There is a Wikipedia article entitled "Early action" about such matters (assuming you trust Wikipedia) which is where I'm getting my info from.</p>
<p>Edit: I'm assuming that the schools mentioned you saw people applying to aren't single-choice.</p>
<p>Aside from a few SCEA schools (stanford, yale, etc.), it is perfectly fine to apply to multiple EA schools and an ED school. Some ED schools, however, won't allow this, so you have to check with your particular schools. But for the most part it's perfectly legal.</p>
<p>Actually, you can apply to any number of EA schools (as long as they are not SCEA), RD schools, and an ED school (or SCEA school that does not limit other applications).</p>
<p>It is legal, and smart to use RD, EA (not SCEA), ED, and Rolling admissions so that one has a choice (whether you are ultimately defered/denied/accepted by an ED/SCEA school). This makes the second half of senior year less stressful, and reduces the likelihood of scrambling to get other applications done after finding out whether you got into an ED (or SCEA) school.</p>
