Size of the Waitlist?

<p>I have a question about being waitlisted. Assume, hypothetically, that I am waitlisted at Princeton. I’m not really sure if I want to attend, and since Princeton probably won’t tell me if I am accepted from the waitlist until after May 1st (candidate’s reply date for most schools), does that mean that I should opt to remove myself from the waitlist?</p>

<p>I mean, how can people afford to stay on the waitlist? If they don’t get in, won’t they have missed the opportunity to reply to another school (besides a state school)?</p>
