Association of biochemistry grades with performance in pharmacology and anatomy in a Saudi Arabian medical college

The College of Medicine, King Khalid University of Abha, Saudi Arabia currently accepts 100 students a year, up from 50 to 70 students four years ago. The first-year students take four science courses (Biology,Chemistry, Physics, and Statistics) in addition to some general university requirement courses. Biochemistry is offered in the second year, Anatomy in the second and third year and Pharmacology in the fourth year. This study was carried out to determine the correlation between the performance of medical students in Biochemistry and their performance in Anatomy and Pharmacology. Data were obtained from two groups of students (Group 22 and 23) of the years 1995 and 1996 who had already taken Biochemistry, Anatomy and Pharmacology. Performance was equal in Pharmacology but in biochemistry performance of group 23 was clearly lower than group 22. Scores of students in Biochemistry course strongly correlated with the basic Pharmacology course (r=0.714, P<0.0001). Scores in Anatomy also correlated with those in Biochemistry (r=0.616, P<0.001) but much less with scores in Pharmacology (r=0.345, P<0.01).
