I graduated in 2009 and started as a sailor. I heard that you have to take three certificates first. I'll take the exam myself first. I don't want to sign up for any training class, I can sign up for the exam myself. There are no self-study classes and compulsory training (STCW requirements). I can take exams every month. The shortest training period is said to be 1 year, provided that science and engineering graduates are fresh. If not, according to the information I know at present, I have to study full-time for at least two years. The specific examination schedule shall be applied by the training institution to the Maritime Safety Administration.
