Yes. We will normally expect candidates to have Chemistry A-level (or equivalent qualification), unless they have a first degree that includes a substantial component of chemistry or biochemistry. The medical course makes no provision to teach A-level science. It should be quite easy for graduates to bring themselves up to the level of competence required, and to take an A-level during the year before they start the course. We will normally expect two science A-levels (including chemistry), and GCSE in biology or dual-award science, or equivalent.
