It's better to go with B.Sc. Nautical Science degree as it is of more importance. B.Sc. In Nautical Science is a 3-year undergraduate course which is split into 6 semesters. Each year consists of 2 semesters and contains a thoroughly practical approach to all the concepts of Nautical Technology.
Thanks.
