“Seagull CES marine test online about ECDIS System” (Crew Evaluation Test) will help marine specialists in preparation to exams for getting certificate of confidence.

This test contains 48 questions. Mode “Practice” and “Exam” have one difference – in “Exam” mode you can’t ask the computer to show you the right answer.

Choose mode in which you want take CES test:
