<p>The common app does have a spot for 6 AP scores. If you have taken an AP and do not list it there, then I think they would assume you have not done well or did not take the test. I don’t think a 3 hurts unless you have as many 3’s as 5’s let’s say…or maybe more 3’s than 5’s. I don’t think 1 thing on an application will hurt most…but it’s one thing and my guess is the limit is pretty low. I think that 1’s would give adcoms a reason to pause and question why… and I do think several 1’s would hurt. However, it’s a new story now that the question appears on the common app. as to what role AP scores will play in admissions.</p>
