Examiners report
There was a wide range of answers about factors causing CHDs and the majority of candidates gained all marks despite the fact that many answers did not really outline how these factors acted and could differ between the different populations. Candidates were not penalized for their obvious and general lack of knowledge about the habits of the two populations.
Most candidates gained at least one mark for the digestive glands, but many answers contained incorrect (e.g. endocrine gland, liver, bile duct) or too vague (e.g. intestine) elements.
