<p>So I asked a professor I worked with over the summer to write a supplemental rec and I'm fairly certain he sent it just before the Nov. 1 deadline. I called in on Friday and MIT said they hadn't received any supplemental recs, but all of my other materials had arrived.</p>
<p>I did ask the professor to include my name and DOB, but it's possible he only put the name. My name is pretty unique, but if they can't match the letter with my file, does the letter disappear? Also, since the rest of my app is complete, if the rec arrives and MIT has already read and summarized my app, will the rec be considered?</p>
<p>I'll call again at the end of this week to see if it's there, since I know not everything has been processed yet, but just thought I'd ask about this in the meantime.</p>
