Hello student!!

As per your query I would like to inform you that if you wish to choose Merchant Navy as a career option you need to pass your class XII with Physics, Chemistry and Mathematics as compulsory subjects and your age must be between 17 and 25 years. Some of the entrance exams for Merchant Navy are Indian Maritime University Common Entrance Test (IMUCET), JEE - Advanced, All India Merchant Navy Entrance Test (AIMNET).

Hope it helps!!
