Afterschool activity

In The Sims 3: Generations, children and teens can enroll themselves (or be enrolled by a guardian) in after school classes and activities, either by entering the school or by using a computer.

Once enrolled in an after school class, students will spend an extra 2 hours in school every Monday, Tuesday, and Wednesday learning a special set of skills. Students or their guardians can quit the class either by visiting the school or using a computer.
