<p>Is it really 300 words? I can't find that rule anywhere I look?</p>
<p>I didn't see any word limit on the common app NU supplement. But I guess anything under 500 should be fine. Except I think under 400 would be more ideal.
I say 500 because that's what cornell has for their essay so I'm thinking it wouldn't be too far from Northwestern's.</p>
<p>My supplement was 630 words and I got in. But try to be as concise as possible.</p>
