Sending the SAT or ACT score

<p>I'm debating which score I should send between SAT and ACT
My SAT score is:
- 570 reading
- 660 math
- 490 writing</p>

<p>My ACT composite is 25
- 25 English
- 27 Math
- 21 Reading
- 25 Science
- 24 Combined English/Writing</p>

<p>I'm submitting for USC. I know this score is probably not good enough but it would not hurt to try. So, which score will realistically give me a better chance?</p>
