In all other examinations the essay style questions are shorter. For example, you might be asked to answer four essay style questions in a 3 hour exam see the Microbiology 3m examination papers, for example . These essay style questions require a large amount of relevant factual information, and understanding of the subject. However, you would not be expected to produce a polished and grammatically correct essay. The important thing is to write down as much relevant information as possible, while sticking rigidly to the question that was set.
