<p>To sum it up, this is the type of thing you need to call Admissions or Housing to ask. It will be very hard to make absolutely sure you get a single all four years that you’re here no matter where you rotate into. The only way to ensure it would be to see if Housing would give you a medical provision and allow you to live in Avery while rotating into another house (or possibly Avery). Braun is grad students only and Marks is upperclassmen only.</p>
