How does Andover or Exeter guarantee your admission?

<p>I mean, if you are in a prep school, there is so much competition, it is difficult to get good grades and get a good rank. And there will be so many activities but all filled.</p>

<p>Or?
My friend attends a prep school, and he does not like it there.</p>

<p>Guarantee your admission where? I don’t understand the question. If you mean your admission to your dream college, they don’t guarantee that!</p>

<p>yeah, i don’t understand the question either…</p>
