Three questions (One involving the October TOEFL)

<ol>
<li><p>Is it alright for me to send in the Common App before the supplements?</p></li>
<li><p>Do I have to send in the supplements (including SAT/TOEFL results) before the application deadline or is it alright if I send them in later?</p></li>
<li><p>I took the TOEFL (I'm an international student) in October this year, but I've yet to receive the scores by mail. Has anyone else had this problem?</p></li>
</ol>

<p>Bump, anyone?</p>
