It really depends on how thoroughly you’ve reviewed the tests before and how much time has passed. For three months and assuming you reviewed the test, I would expect a 1-2 point increase per section but this can vary. Remembering five questions consciously or subconsciously in the 125 score range could bump you to a 126, but those same 5 questions could bump your score from a 130 to a 132*, so it’s hard to predict. This isn’t to say that you shouldn’t retake the test but that using it as a predictor of how you may score is a bit less clear. For retakes I tend to encourage folks to look at the trend of their scores across multiple practice tests.
