<p>Aha! 
I’m doing something similar (waiting on October ACT results for SCEA, already sent all my SAT scores).</p>
<p>In that case, I don’t think it would hurt to wait. Just be sure to send it right away once you receive it if you’re happy with the score. :)</p>
<p>Honestly, though, if it’s comparable to your SAT scores, it’s not really worth the money of sending it. :</p>
