No, you do not need to have a roommate selected before room selection. When you have access to room selection in May, you will be able to see the name, major, age and smoking preferences of the student(s) already assigned to the room. You are able to select and change your room as many times as you’d like through July 1. If no roommate is assigned to your chosen room, you should be ready to accept a random roommate at any time.
