If it is simply to not waste the opportunity to apply for the exam, it is not worth it. Generally, only a few maritime colleges enroll students in advance, such as Dalian Maritime University, Shanghai Maritime University, Wuhan University of Technology, Jimei University, etc., but they are not the mainstream schools of navigation.
The school adopts semi-military management and unifies one day a week. After graduation, the employment is mainly to drive a ship, serve a shipping company or be a crew member under a crew management company. Basic graduates of undergraduate colleges go to ocean-going ships, which can travel around the world on the one hand and endure the boring life at sea on the other.
Conditions for applying for maritime majors in advance:
Navigation technology majors require normal color vision (no color blindness, colorless weakness), no diplopia, height1.65m or above, naked eye vision of both eyes of 4.7(0.5) or above, and corrected vision of 4.9(0.8) or above.
Marine engineering (marine engineering specialty) and marine electronic and electrical specialty require no color blindness or diplopia, height 1.60m or above, binocular naked vision of 4.6(0.4) or above, and corrected vision of 4.8(0.6) or above.
