Physics SAT II Score

Hello fellow College Confidential users. I have taken both the Physics SAT II and the Math II one, getting 700 and 800 respectively. The only two schools that I’m applying to that need the scores are University of Pennsylvania and Stanford. I did so poorly on the Physics test because we didn’t cover all of the material in class. I am concerned that colleges might consider physics a weakness for me because of the score as well as my grade in my class (B+) even though I am currently taking a class that is designed to prepare students for the AP Physics C exam. What’s your advice? Should I retake it or would my time be better spent elsewhere? I’m planning on majoring in economics FYI and have an act score of 34 (35E, 34M, 30R, 35S, 10W).
