Do I have to send in all SAT IIs?

<p>Hi everyone,
So I know USC requires all scores, but they also say that SAT IIs aren't required, so I am wondering if I have to send in all SAT II scores. My problem is that I have two really good scores (770 and 710) but two really bad ones (650 and 620 which are both in math 2 oops)? Also, if I have to send in all scores, should I just not send in any because of my low scores, or should I send in all scores?</p>

<p>Thanks!</p>
