Assessment

1. an aggregate mark of 50% or more, and
2. Obtain at least 40% in the final exam, and 
3. Obtain at least 40% of the possible marks for the laboratory hurdle.

Students who do not successfully achieve hurdle requirement 2 and 3 in full, will receive a maximum of 45% as the total mark for the unit.
