They're all above 125. I recommend not retaking the test and focus on improving other aspects of your application (clinical experience, community service, secondaries, interview prep, etc). A lot of students who retake study for several months and barely see 2-3 points improvement. If your FL average was 515 but you got 4 points lower, then I would definitely recommend retaking. However, your FL average was 507 and you saw a 4-point increase. It's too risky to retake. There is a reason why people say trust your FL average. If you retake, it might work against you.
