Diploma Course Assessment

Your understanding of the course will be continuously assessed as you work through the modules. After you have studied each individual module you will complete a multiple choice test that covers the information from that section. Your answers for each module test will be automatically marked and the results displayed on a bar chart. This assessment procedure will apply to all eleven of the course modules. To finish the course you will need to submit a research thesis as outlined in the summative task.
