<p>I know that many people say that AP exam grades do count, but very little and are mainly used to see if you are eligible for exemption from classes once you are accepted into college. However, I was wondering if anyone could tell me how much exactly will these grades affect an admissions decision? For example, if my dream school is Yale, and I happen to have gotten a 4 on one of my AP exams, will this significantly lower my chances? Thank you.</p>
<p>A 4 will not significantly lower your chances at any college by any means. SAT II scores are the ones you should worry more about.</p>
