<p>Sending your scores are completely optional (some schools allow their students to take AP courses but don't make it mandatory to take the exam).</p>
<p>It is not unusual for students not to send the scores, so adcoms will not think that your transcript is not legit, they are merely just evaluating the information they have before them.</p>
<p>Unless you have 5's at most selective universities you won't be able to use your aps for credit.</p>
