<p>I decided to send in a theatrical supplement, but is it too late? Thanks so much</p>
<p>I’m not very sure, but it seems that you should have checked the supplementary materials box on the Common App if you wanted to send a supplement. I’d call the Admission Office to ask them whether they’d accept it without the check.
As for being late, I think you’ll be ok because the materials need to be postmarked by 31st. </p>
<p>And btw, Harvard says that students should not send video recordings of musical performances or recitals.</p>
<p>It’s not too late because they need to be sent by the deadline, not received. But yeah, if you didn’t check in your application that you’re sending supplementary stuff, then you should contact admissions.</p>
