<p>Don't worry about it. Mail it after. Alternatively, don't send it at all. When they ask you for it, say it got lost in the mail and fax it to them.</p>
<p>Remember, many colleges are closed till Jan. 2 anyway. Then they have mountains of mail to process and sort. As long as you get it sent when school reopens, I wouldn't worry. Also, lots of times kids are informed that something is missing from their file and they have to ask their school to resend it - things get lost. Admissions Committees will start reading files that are complete, and when yours is, it will get added to the stack. Don't worry.</p>
