Achievement in pharmacology tests according to educational background. Students with a background in Biomedical Sciences performed significantly better both at the pre- and post-test (test range 0–50), as compared to those with no background in the Biomedical Sciences. Similarly, students with post-graduate degrees performed better at the pre-test but no difference was noted at the post-test, suggesting that all students benefited from the PBL curriculum independently of level of education. However, a background in Biomedical Sciences was advantageous in the learning of pharmacology at the end of the year.
