1, make up the difference, that is, through knowledge update training. It includes electronic charts, bridge resource management, new navigation instruments, laws and regulations. There is also the renewal of certificates and basic security. It takes about 10 days of training. There are two practical tests (electronic chart, bridge resource management). 1 theory test (all theories of the above subjects, 50 questions, X2 score, 60 points passed, maritime bureau computer test).
