<li><p>If it is a LL from a Ivy League school, your daughter will most likely have to submit a completed application, early action or early decision. The letter is a guarantee of admission. It can be rescinded only for reasons that they can rescind a formal offer of admission (e.g. significant degradation of academic performance, disciplinary issues, etc.).</p></li>
<li><p>It doesn’t mean she has compete. She doesn’t have to sign anything.</p></li>
