Retake PHysics Subject test?

<p>I'm a senior applying Early Decision to the Cornell College of engineering. My SAT Subject test for physics is a 710. Is it worth it to retake it in october or november (yes, cornell ED accepts november scores as said by admissions office)? I also got a 700 on u.s. If i retake physics i might retake that as well. My math ii is 780 so im good there. But is it that much different if i get a 780-800 on the retake ?</p>
