I want to go to Barnard College but I feel like my extracurriculars are lacking?
Depends on what you want to study, but also just depends on you as a person. Do an extracurricular you want to do. Don't try to stuff yourself into roles and groups you really have no interest in being part of just for the sake of looking good. There's not really a "right answer" for extracurriculars; pick something you can stick with and that you have passion for, and the rest will flow naturally when it comes time to apply :)
