Quotas?

Are there limits to how many students a college will accept from a single high school? I realize if there are great kids equally qualified a school will want them, yet it seems some schools only get 1 student into yale and 1 into Brown etc. Do some schools set limits? Does high school size matter or school ranking? What are the other factors?

<p>there are no SET quotas, but schools that are all for diversity will not want to take in too many from one school to make sure they've got geographic diversity.</p>
