The application of online learning solutions creates anxiety for students. Online courses help students to become solutions during the COVID-19 pandemic because they are practical and can be used anytime and anywhere. The purpose of this study was to determine the level of math anxiety experienced by students who took online courses and those who did not take online courses. The method used in this study was quantitative by using a survey to determine the level of math anxiety of grade 9 students. The sample used in this study was 129 grade 9 students at SMPN 141 Jakarta. The results showed that of the five indicators, the highest indicators were learning activities for students who took online courses (x ̅=3.41) and students who did not take online courses (x ̅=3.85). The results of the study show that overall students' math anxiety in online learning is in the moderate category.</p> <p> </p> <p>Kecemasan matematika dapat menganggu proses pembelajaran dan menimbulkan dampak negatif bagi siswa yaitu dengan menghindar dari hal yang membuat siswa merasa cemas dan juga menghasilkan pembelajaran yang kurang efektif.
