Background: Many students could not manage their times efficiently before being students in college since they did not have any challenges or difficulties in high school. However, the case changed completely when they are attending college. Being a student in college means that the responsibility is bigger and the courses are more difficult than what they were in high school. Aim: The research aimed to determine the relationship between the time management skills and academic performance of students, to assess time management and practice among students, to determine patterns of time management among Jazan University students. In addition to determine whether student participation in extra-curricular activities and social media correlates to his or her cumulative grade point average (CGPA). Method: The study design is a cross-sectional study of the effect of time management on academic performance. Conducted it in Jazan University for medical and non-medical students. Results: The study conducted on 491 participants of female (53.80%) and male (46.20%) students. The Applied Medical Science students (24.20%) stated that they just consumed their time to complete homework, while Faculty of Science students (9.40%) reported that they rarely have time to do. We find that 44.2% of male and 65% of female never participate in student club, while 43.50% of male and 15.60% of female always do sports and 12.90% of male and 4.20% of female always planning for these activities. Conclusion: Students who had opportunities to practice time management skills revield better academic performance in addition to the differences in the time management level between students according to faculty, gender and curriculum.
