Objective: Investigate the influence of the stressors caused by the Covid-19 pandemic on the academic performance of undergraduate students, and their ability to concentrate on schoolwork.Participants: 1,806 students attending a racially diverse 4-year university with a high rate of first generation college students.Methods: An online survey utilizing measures of depression (PHQ-9), generalized anxiety (GAD-7), faculty and academic advising support, economic insecurity, studying conditions, family conditions, trouble concentrating on schoolwork, and academic performance. OLS regression is used to explain academic performance and trouble concentrating. Results: Four of five students reported trouble concentrating, and trouble concentrating strongly decreased academic performance. Faculty and peer advising support and adequate studying conditions improved academic performance. Depression strongly increased trouble concentrating. Adequate studying conditions and academic advising support improved concentration.Conclusions: In the upcoming year, faculty and student support services should highlight mental health issues and services, and increase supports for students experiencing distress.
