text: Students must participate in at least one extracurricular activity because it will look good on their applications. When universities look at your grades, they also look to see if you participated in other activities. For example, if you joined a club that had to do with public speaking, universities would think that you're able to present in front of a class, and jobs would think that you would do well in customer service. All these small things help you in your future. When you join an after school club, you will be able to have a lot of activities on your applications.
