<p>is there any special weight added to someone's app who got a letter of rec from a columbia professor that they did research with?</p>
<p>I hope so, I'm submitting one too.</p>
<p>Definitely -- that'll stand out and give you credibility. Everyone has great recs, so the credible ones really stand out.</p>
<p>Got one from a yale pro I worked with. Accepted ED.</p>
