College (rabbit hole)
A classroom is a rabbit hole added in The Sims 3: University Life that only appear in the university. Sims can attend classes, skill classes, or class activities. However, lecture halls can be seen inside. There is also an administration center where Sims can ask to reassign their roomates or clear their name from cheating. Each classroom is marked with a different looking tab. Sims can also become test subjects at the School of Science.
