Just Another Question about AP's

Lets say that I’ve taken a boatload of AP classes/tests and that around half of the scores are 5’s and the rest are 4’s (worst case scenario one 3). Assuming I wanted to apply for Ivy universities, how much would it help if some of those 4’s became 5’s instead?

Don’t retake. 4s and 5s show that you’re qualified enough for an Ivy. If anything, retake ONLY if you need a 5 for credit in a certain college class.
