<p>Will I have write a new set of essays?
Will I have to ask for recommendations again?
Will I have to go through all that application process again?
(That would be bad lol)</p>
<p>You don't have to do anything if you're deferred from EA. Your application is carried over into the RD pile and is considered all over again. You have the <em>option</em> of sending an update to be included in your file, but it's not required. It's also not recommended if all you're sending is a rehash of what's there already: if there are any new accomplishments or new news that happened since the EA submission deadline and should be included, definitely send a written update to Admissions. Otherwise, no need to do anything further!</p>
