Any Sim that is a young adult or older can decide to go to college, and if they decide to go they will be transported out of the game’s main town into a separate town where the college exists. Once in the new college town area, Sims can either live in dorms, get their own apartment, or join a sorority or frat house. Living in close quarters with lots of other Sims can be a major pain, just like in real life, and now Sims can annoy their roommates to clean up after themselves.
The actual classes and studying function almost identical to current jobs and schooling that Sims can do in the regular game. Once a Sim earns enough credits to get a degree, they will be able to start out in their chosen career with a higher salary.
