<p>I am so confused about this process.</p>
<p>So there's a university, and the university, let's use Duke for an example, has Trinity College of A&S and Pratt Engineering.</p>
<p>When you apply to Duke, do you gain admission to Duke university, or do you gain admission to Trinity?</p>
<p>I.e. if you get rejected from one school due to demand, are you rejected from the entire uni? Can you go to another school?</p>
<p>Also can you take three classes from Trinity and one from Pratt if you're techincially "enrolled" in Trinity?</p>
<p>Thanks so much for helping!</p>
