Have to submit in all SAT II's to colleges that request ALL SCORES?

<p>Hi! So I am so confused as to what colleges mean when they say send in all scores.
I know that I will have to send in all of my SAT scores but do i have to send in all of my SAT II scores?
For instance UPENN requires all scores + 2 subject tests
does that mean I have to send all 5 of my subjects tests I took or I can pick and choose and send 2 of them?
Also when UPENN says Wharton applications are highly recommended to take the Subject test Math Level 2 would it hurt my chances if I did not take that test?</p>
