The Diamond Course 22 Diamond Council of America © 1 Final Review

If you’re among the sizable percentage of adult learners who feel somewhat anxious at the prospect of structured testing, relax. You’ve already done a great job on the 20 Lesson Self-Tests and the four Learning Evaluations. You can expect to do equally well on the exam. If you think you may have forgotten how to study for tests, you’re not alone in that, either. This review will walk you through the process and give you some helpful guidelines. When you’ve finished, you’ll be ready for a successful examination.

Exam Options When you have successfully completed all four Progress Evaluations, you are eligible to take the Final Examination. The exam consists of multiple-choice questions just like the ones on the Learning Evaluations. The testing procedure and the number of questions depend on how you decide to take the exam, and there are two basic options: • Open-Book Exam – You take the exam without supervision and you can look through the course to find answers. If you choose this option, the exam will have 150 questions. Open-book exams may be taken online or by mail. Your review will help you organize your study, • Closed-Book Exam – You take the exam under identify the main points of each lesson, and recognize areas that need further attention. the supervision of a proctor designated by your company, and you cannot check the lessons or other references. If you choose this option, the exam will have 100 questions and you will receive special recognition from DCA. Closed-book exams can only be taken by mail.

Most students take the exam open-book. If you completed your Learning Evaluations online, you’ll be given access to the online version of the open-book exam. If you completed the Learning Evaluations by mail, DCA will send you a printed (hardcopy) exam. However, you may take an open-book exam whichever way you prefer. If you completed the evaluations online and want a hardcopy exam, or you completed the evaluations by mail and want an online exam, you can contact DCA and all the arrangements will be made. You will also need to notify DCA if you want a closed-book exam. You can do this by signing the Request for Closed-Book Exam that is at the end of Training Evaluation 4, or you can contact DCA and make the request.

Grading and Completion The Final Examination is graded like the Learning Evaluations. The grade you receive will be a percentage based on correct versus total answers. There are two limits on course completion that you need to keep in mind: • Academic Limit – The minimum grade target for the Final Examination is 75%. If your grade is less than that, you may retake the exam once. If you do not reach or exceed the target on the second attempt, you must re-enroll in order to complete the course. • Time Limit – All of the coursework, including the Final Examination, must be completed within 12 A good way to begin the review of each consecutive months from the date of enrollment. If lesson is running down the checklists and you do not meet the time limit, you must re-enroll in marking off items you’re confident you know. order to complete the course. (Your completion deadline is noted on The Diamond Course Instruction Sheet that came with your printed course materials, and on the "Welcome" page of the online Student Testing Center. You can also obtain the date from DCA.) The Diamond Course 22 Diamond Council of America © 3 Final Review

Studying for the Exam

You’ve probably been using many things you learned in the course. Normally, you don’t need to study what you already know so your review should go fairly quickly. You might need to re-read a few lessons closely, and you’re likely to discover some facts you overlooked when you first studied the material. There’s no substitute for being prepared for your exam. “Cramming” the night before probably won’t do much more than rob you of good sleep. This review is designed to send you into the exam well-informed and confident. It will help you organize your study, identify the main points of each lesson, and recognize areas that need further attention. Before you start, let’s recap some of the study tips you received in Lesson 1: • Set your review schedule and stick to it. • Pick a quiet, comfortable place to study. • Whenever your attention begins to lag, take a short break.

The next section of this lesson includes checklists of key terms and facts for every lesson in the course. The best approach is to review one lesson at a time. If you’re going to take the exam open-book, you might aim at covering four lessons per study session. That way you’ll complete the review process in about five days. If you’ve decided to take the exam closed-book, it’s probably better to tackle two lessons per session, so your energy and retention stay high. A good way to begin the review of each lesson is to run down the checklists and mark off items you’re confident you know. Then go back to the lesson and look up anything you’re not sure about. Make brief notes or highlight the material to reinforce your memory. Be sure to review your Self-Tests, Learning Evaluations, and the Learning Evaluation Feedback you have received. Give extra attention to any questions you answered incorrectly. The Diamond Course 22 4 Diamond Council of America © Final Review

If you’re taking the exam open-book, your main concern is knowing where to find information. If you’ve chosen the closed-book option you need to continue through the checklists until you’ve marked off everything, and you’re able to respond to each item without looking back at the course material. For extra practice, you might give this review to a coworker or friend and ask them to quiz you. If you have questions or concerns about the Final Examination or any other aspect of your coursework, please contact DCA.
