<p>If your teacher sends it out on Nov. 1 (in the morning), it should be fine. Even if you sent out your materials (app, supplement, etc.) on Nov. 1 (in the morning), it should be fine because that’s just the postmark deadline, not the date that they have to receive your materials. Remember, the mail still runs on Saturdays so it shouldn’t be an issue at all. At least this is according to their website (look under “when to apply”): [Application</a> to Yale College | Freshmen | Office of Undergraduate Admissions](<a href=“http://www.yale.edu/admit/freshmen/application/index.html#when]Application”>http://www.yale.edu/admit/freshmen/application/index.html#when).</p>
