The use of "MapleTA"[R] in the assessment of engineering mathematics at Liverpool John Moores University (JMU) is discussed with particular reference to the design of questions. Key aspects in the formulation and coding of questions are considered. Problems associated with the submission of symbolic answers, the use of randomly generated numbers in questions and the strategy of setting policies are all discussed. Some examples of questions are then given for illustration purposes. Discussion of peripheral aspects of the implementation of "MapleTA"[R] in assessment is also presented.
