Examiners report

Few candidates were able to demonstrate the subject-specific vocabulary required to answer this question with clarity. Most did not refer to the cerebral cortex or even cerebrum, instead using vague terms like “brain.” Where students added detail, it was often about the frontal lobe, something this question was not addressing.
