Ermmm application? when, exactly? please!

<p>Hey,
So I'm sorry if my questions may sound stupid, but I'm a US Citizen living abroad, attending a British School who knows nothing about the US universities application process, and my parents didn't go to the US for undergrad.</p>

<p>So I was wondering:
1) If i apply ED, do i have to submit my SAT II scores to universities that require it right away? or can i send those at a later date?</p>

<p>2)When should i really start sending applications into ivy leagues.. October? November? </p>

<p>3) How is it possible to send the common app, but send the "essays" later, as there are a few universities that said "you may submit your common app, but your answer to the short question (on ECs) and essay can be submitted at a later date". So i just skip those when i send it?</p>

<p>4) If i'm doing the common app online, how do i get the sheets for teacher recommendations? Do my teachers have to copy down the same recommendation on say, 8 sheets if i'm applying to eight universities, or can they photocopy?</p>

<p>Any answers would be more than helpful to me, thanks!</p>
