The coursework assessment comprises two class tests. A grade will be awarded for each test and an average coursework grade will be computed by weighting the two tests equally.

  • If you gain an overall coursework average of at least 65%, you will be exempt from the examination. Your final grade will be your overall coursework grade.
  • If you do not meet the above condition, you should take the examination. Your module grade will be computed by weighting the components of assessment as follows: coursework 40%, examination 60%. You must get a weighted grade of at least 40% for an overall module pass.
