<p>I'm confused about how USC chooses your roommate. I filled out the housing stuff and I understand they have a app where you can find people with similar answers on the surver and request to be their roommate. I'm wondering though if you don't find someone through the app does USC just match you with someone randomly or do they still use the survey results? Also whats the point in the matching app if you don't know where you will be staying?</p>
