Assessment Rationale And Relationship

The exam tests acquisition of a clear general knowledge of the subject plus the ability to think and analyse a problem quickly, to select from and to apply both the general knowledge and detailed knowledge of aspects of the subject. The exam also assesses problem solving skills, the ability to work unaided and to communicate clearly and concisely in writing.
The Graduate Skills Framework entries indicated as 'A' are also assessed in this way.
