<p>Assume that a student sent the acceptance deposit to school A on April 15th. In the last week of April, he decides that school B is the right one. Can he withdraw from school A (say, by writing a letter) and send in a deposit to school B? If yes, suppose further that he is selected from the waiting list to go to school C in early June. Can he then withdraw from B and accept admission to C? Is this is all legal/ethical? Note that there is no double-dipping. The student is not sending the deposits simultaneously to more than one school.
I'd appreciate response from knowledgeable people. Thanks.</p>
<p>Perfectly fine</p>
<p>Yes, it's fine. As long as you don't double deposit to 2 schools, you're fine. You'll lose your deposit from the school that you decided not to attend, but that's a small price to pay for going to your preferred school. Happens all the time when students get off wait lists.</p>
