Is it worth it to submit poor SAT subject test scores?

Penn recommends 2 subject tests, yet I recently got my scores back and they are quite disappointing:

680 Literature
670 US History
570 Spanish

Will submitting poor SAT II scores hurt my application? Will not submitting any hurt it more?

Will the AP Scores that I’m submitting (APUSH-5, APUSGov(Self Study)-5, APEuroHistory-4) stand in lieu of a lack of subject tests?

Thanks

I think you shouldn’t submit these. they are just a little bit low, and they might dilute your excellent AP scores

Yes.

A matter of speculation. But I would not submit them. Good luck.
