Should I retake my Chemistry regents?

I love Chemistry and I took the regents (NY state test) and got on the Mastery Level (86-100). I got 86 which is actually an accomplishment for the Chemistry regents. It is being re offered tomorrow and I can't decide if I should retake it and aim higher or if I should stick with what I have. After not studying all summer and being preoccupied, I am kind of rethinking taking the exam. Does anyone have any advice on the matter? Do colleges really care about the 4 point difference between an 86 and a 90?
