The difficult transition from high school to university means that many students need to repeat (retake) 1 or more of their university courses. The authors examine the performance of students repeating first-year core courses in an undergraduate business program. They used data from university records for 116 students who took a total of 232 repeated courses across 6 subjects. The results show that the students' original course grades and cumulative grade point averages were positively associated with the new grades obtained in the repeated courses. Conversely, the original course grades were negatively associated with the extent of improvement obtained by repeating.
