Examiners report
Generally well answered but some too vague such as referring to “heart problems” rather than specifically outlining a heart problem.
I was disappointed with the number of candidates that did not know what beta blockers were. Some confused them with diuretics, others with muscle-enhancing substances. Those who did know, generally answered it very well and obtained full marks.
