CBM Part 4 consists of a written analysis of a Harvard Business School Case Study. Upon registering for CBM Part 4, you will be provided with five sample cases, and you can submit your analysis to us for grading. We will provide feedback to you so that you can gauge your progress. In the actual certification exam, you will be provided with a different case for you to answer, using all that you have learned in CBM Parts 1, 2, and 3. The case used is very similar to that used in exams at the top Business Schools worldwide.
