I need some advice

<p>First off, i'm applying to nyu stern (yeah, I know so many people are). I took the act's twice and got a 31 both times but here's the breakdown
31 eng
33 math
30 reading
29 science </p>

<p>the second time:
34 english
33 math
33 reading
24 SCIENCE</p>

<p>Should I send both scores and say in the explanation part that i sent both because I know i'm capable of scoring higher in the science section. If I can't send both, which one looks better to send? the 24 is killling me</p>

<p>is a 31 even a competitive score at nyu stern?</p>
