Thanks; As my co Author and friend Paul Allen has pointed out, we designed the book to cover all aspects of the OCMJEA 6 exam and to provide the reader with sufficient material (including practice exams) in order to pass all three parts. The essays are good models to use to answer part 3. We also provide lots of modeling in part 2 review and chapter on UML which was based on real world / practical applications.
