But our school's major in ocean is of course the best, otherwise we can't live up to the words "national prefix" and "ocean". There are two majors in our school that are the best for employment, namely, ships and port waterways, which are very good for employment and are also very good majors in our school. Of course, there are certain requirements for grades. If your grades are ok and you want to find a good job in the future, apply for the above-mentioned marine major. As for mathematics, as far as I know, employment is generally not very good.
I hope the answer will satisfy you, and I hope we can meet again in September.
