The development of social media applications has made it an important part of students' personal lives. In this article, we aim to determine whether social media usage is beneficial or harmful to college students through academic performance. Through a survey of biological undergraduates, we found that boys use social media applications more frequently than girls, and that GPA is inversely related to the number of social media applications that students subscribe to. In addition, we found that using more social media applications is positively related to the amount of time spent on social media per day. Our research shows that social media may have a negative impact on undergraduates' study habits and academic performance.
