<p>I was looking at this year's Peterson and for fall 2005:</p>
<p>Deerfield: 1753 applied, 360 accepted, 201 enrolled.
Andover: 2229 applied, 469 accepted, 347 enrolled.
other schools similar.</p>
<p>Thus it would appear that they accept about 120 - 160 MORE students than they enroll - thus it would appear that chances of being accepted from waiting list is very slim.</p>
