It really does not matter. IB/AP scores are processed by a clerical to ascertain credit. You will probably never meet him/her. If on the off chance you bump into him/her on Locust Walk, s/he will not think, “Oh, that’s the kid that got a 2 on IB Math HL.”
Your acceptance will not be rescinded, so there are better things to spend your time contemplating. Good luck.
