The merit score included co-curricular activity at university. The merit score was determined based on the activity involved during their academic session by university students. The study was conducted to determine the influence of the merit score obtained by engaging in campus activities on the academic performance of students and to determine the relationship between academic performance, year, course, and gender. This study of undergraduate students was a cross-sectional study. Stratified random sampling and then accompanied by systematic random sampling were the methods of sampling used. In this study, 174 students participated, with an 85.3 percent response rate. The results of this analysis showed that the merit scores had an overall weak academic performance correlation. However, it is also found that according to the year of study, the merit scores were not statistically significant and that gender and courses was a significant predictor of the merit score. The merit score associated with gender was shown to be the result. Compared to female students, male students are more involved and this can impact their academic performance. In balancing life between co-curricular activities that are required for the creation of generic skills and academic achievement, students should be very thoughtful.
