This study investigates the impact of online learning on postgraduate students' academic performance, which is reflected in their GPA. A survey questionnaire was used to gather quantitative data from 36 participants. The quantitative data were analyzed using SPSS. The results show that there is a statistically significant difference between face-to-face and online learning, which has an impact on the MA TESOL students' academic performance in the Saudi EFL context. Based on the results, the study puts forward recommendations and directions for future research.
