SAT Subject Tests worth it for sure?

<p>SAT Subject Tests, according to NU's site, "tend to offset lower ACT/SAT scores." The thign is, I'm taking 3 sat subjects this saturday (which of course i'm really nervous for), but what if I do well? Not that I wouldn't send them, but I did DREADFUL on the reasoning test (and no, not a 2000..much much much lower.) But i did better on the ACT...wondering if i should send subject tests even if i do really well on them (as in 700+)?</p>

<p>Thanks :D</p>
