<p>yeah it seems like my addt'l rec won't be going in on time either. my recommender was kinda busy and somehow is not available at the moment either so it's prob gonna go in after Jan 1st. I know someone who had their teacher rec sent in 2 weeks after jan 1st and still got into the school (stanford).</p>
<p>but i just used what stanford required on the header of their addt'l rec: name, common app id number, birthdate, and school.</p>
<p>If you really, really think it will make a difference in a positive way, then I guess go for it. But only if the stuff that rec says is different from the others/shows another side of you. </p>
<p>I didn't do the Common App ID number, school, or birthdate-- I just put my SSN on all of my forms/papers.</p>
