Isn’t it time that you experience the written examination in it’s official format? Don’t you wish that you could use practice exams as part of your study? Not just 1 practice exam, but multiple. The written examination is not the hardest exam to pass, but it is the part of any course that causes the most amount of anxiety. Whether you have enrolled in the Open Water Diver, the Divemaster course, or the Instructor Development course, you will at some point be required to pass a written examination. All students who enroll in a scuba diving certification course have to take a final written examination in order to pass their course.
