College Answer

Overall, this question was well answered. Candidates were expected to classify the 
hypersensitivity reactions into their typical groups (Type I – IV) and to describe the 
mechanisms within each group. Similar such questions have been asked in previous exams. 
Again, those candidates who could provide some structure to their answer tended to score 
well.
