SAT subject tests -- should I retake?

I took the three SAT subject tests in May and recently received my scores and am wondering if I should retake them or not.
Literature: minimal preparation and got a 660, placing me in the 58 percentile
Mathematics 2: 680, also with minimal preparation, placing me in the 41 percentile
US History: 730 with lots of preparation, as I was also taking the APUSH exam the day before the subject tests.

The schools I will be submitting these scores to would be Northwestern, Tufts and Georgetown.

I think that I will stick with my US History score and not retake it as I felt decent about it and did a lot of studying and prep so I’m not sure I could improve. However, I’m considering retaking the Literature and especially Math, though the biggest issue for me on math was timing, so I’m not sure how much I could improve my scores.

How will my current scores look to the schools I’m applying to and do you think I should retake it?
If so, what should I do to prep and what scores do you think I should be aiming for?
Thanks so much!

To me, you would be better off perhaps applying to schools that do not require SAT2 tests.

I would think those schools would want higher math/english scores.
make sure to pick out good safety/match schools as well.
