Should I Retake It?

Hey guys,
If I got a 690 on my US History Subject Test, and am planning to apply ED to UPENN, I have pretty much all A’s A-'s and have a community service project that I did independently and it’s pretty impressive. With this and ACT scores over 30, do you think I can get into UPENN. I plan to take 2 other subject tests. So my question is: Should I retake the US History Subject Test? Thanks!

not to mention i’m a minority who goes to one of the most selective and difficult private schools who usually sends kids to ivy leagues (20% usually)
