Do I need to retake or nah?

Hey folks,
I’m a junior (Class of 2017) who took SAT II tests as a sophomore but am only now considering retakes. My scores are 750s on literature and US History. The rest of my application is solid, but this is arguably a weak point. Should I retake if I’m looking at schools like Yale, UChicago, Princeton, Harvard, Stanford, etc.?

Personally, I think your scores are good enough.
