Do AP Exams really matter?

<p>If you pull off a good grade in the class, does sending you ap scores to ivy league/uc/stanford truly improve your chances? Do they like to see us taking the challenge (sending 2s and 3s) or is it bs and should we only send 4s 5s/will 3s look bad? DO you have any evidence that ap scores made or broke an applicant's admission? Thanks!</p>
