The relative role of 'A' level chemistry, physics and biology in the medical course

The performance of 209 students in the 2nd MBBS, first clinical year and final MBBS examinations has been compared retrospectively with their grades in chemistry, physics and biology at 'A' level. The mean grade has also been determined for students from different social classes and secondary education.
Significant differences in marks for biology were found between successful and not so successful students, especially in the pre-clinical part of the course. Significant differences in marks and significant correlations were also found for physics but not to any great extent for chemistry. The relative role of these three basic sciences in the medical course is discussed. The suggestion is made that there is a need for a re-appraisal of the privileged position of chemistry as an unquestioned science requirement for entry to medical school.
