I'd retake, if you don't mind studying more. If you improve your score by 3-4 points the $175 LSAT fee could turn into a couple thousand dollars in scholarships from the right school.
The one benefit is that it can get you fee waivers that you'd otherwise have to apply for or in some cases might not even get if you asked. If that's not worth some spam then don't bother I guess.
I'm working on a lesson about interviews for Admissions Starter. Yes, interviews can be significant, but many schools don't use them. Prominent schools that invite some candidates to interview include Harvard and Chicago.
