<p>How do I send in an additional rec from an advisor who doesn't teach me in any classes? Through common app? or should I just ask her to write me a separate letter?</p>
<p>I think you should ask her to write one. But which college are you applying to? Additional rec letter is “strongly discouraged” for some.</p>
<p>I was thinking about sending an additional letter from the principal, and I think it was supposed to be done on personal stationery. I’d check up on the website to be sure, I think they specified or else I don’t know where I got that information from. </p>
<p>Hope this helps!</p>
