<p>eg1, you can’t change submitted ED (or EA) applications. I think what OP meant is that RD apps were better because they were worked on between the ED and RD deadlines.</p>
<p>To the OP:
When submitting common application, you don’t have to submit it to all the schools at the same time, even if you do it electronically. It is my understanding that you can keep changing your application and submitting it to various schools one at a time (once submitted to a specific school, it can’t be changed for that school). I hope that I am right about it…</p>
