Our 3 day Unit is for mariners who are preparing to test and want to ensure they have the knowledge level necessary to successfully pass all examinations. During the 3 days, mariners will be tested on all topics required as shown on their approval to test letter. Once the mariner completes the practice examinations, considering time is available, our instructors will provide tutoring / guidance on topics that are necessary to review at home prior to testing. This Unit 4 preparation course should be planned at a time close to the testing date to ensure material is retained and / or give the mariner time to review material as directed by the instructor. This is not an instructional preparation course; please refer to our other license preparation options for instructional needs.
