<li><p>Is it possible for me to, let’s say, retake my SAT in the last available date (Jan 24) and just send the scores to the colleges via CollegeBoard, even though on my Common App (which I’ve sent already), it is stated that I’ve done them in Nov?</p></li>
<li><p>Is it suspicious that my teachers have sent my references and evaluations via common app but neither harvard nor brown have them as “received” on their “track your app” websites? Or is it normal? </p></li>

<p>Depends on when your teachers sent the mails, and via what type of shipping. It could have just not reached yet. Or, the admissions office is clogged with loads of mail, and it takes time for the mails to be keyed into the system, so the system has not been updated yet.</p>
