Yes, both marine engineering and navigation technology are semi-militarized. They must wear uniforms and carry uniform schoolbags. If you want to wear school uniforms in class during the day, you don't have to wear them after class. Classes line up in the classroom. If there is a study task, the college will also arrange for students to study by themselves in the morning and evening. However, this management model will not last for four years. Usually, the school is a little strict with freshmen. By the beginning of sophomore year, especially the beginning of sophomore semester, they will almost be ignored, and students will be just like ordinary college students. Junior year is more relaxed, no self-study and no need to wear school uniforms. However, in the senior year, although the management system is loose and the single subject study is tense, our water majors have to take the national unified sailor certificate examination. Of course, in the previous three years of study, there have also been small-scale vocational qualification certificate evaluation exams, which must be passed, otherwise they cannot graduate. Don't worry, it's not difficult as long as you have a class. That's how I got here. If you are a marine engineering major, these courses are extremely important: marine diesel engine (junior), marine auxiliary equipment, marine English, marine electricity, marine engineering foundation, ship management, thermal energy and power engineering, marine engineering materials and mechanical design, because some courses will be tested later, and some are very important professional basic courses, which are difficult to some extent.
