History of Not Completing Courses as Predictor of Academic Difficulty among First-Year Students.

: The study reported here was undertaken to determine whether the prediction of academic difficulty in the first year of medical school is enhanced by a consideration of the number of courses withdrawn from, repeated courses, and incomplete courses on a student's undergraduate academic record. All students enrolled from 1981 through 1985 at Southern Illinois University School of Medicine who experienced academic difficulty in the first year were selected for the study. Successful students were matched with these students in terms of minority or majority status and served as a control group. Discriminant and classification analyses were performed in a hierarchical stepwise manner to predict success or difficulty in the first year. The variables that were significant in discriminating between minority students who had academic difficulty and those who did not were the science grade-point average (grades in biology, chemistry, physics, and mathematics), the score on the reading subtest of the Medical College Admission Test (MCAT), and the number of withdrawals from courses. For majority students, the significant discriminating variables were the score on the MCAT biology subtest and the number of incompletes taken for courses. The results of this study have implications for medical school admissions committees, premedical advisers, and premedical students.
