These may be arranged differently in each training center. You can consult if you want to know. I don't know where you are from, as I reported in Nanjing Sunset last year, it passed smoothly. There are systematic intensive classes and agreement packages (if the agreement is signed, it will be refunded), and the training is generally arranged on weekends and evenings. Personally, I feel that since I want to enroll in the training class, I have to coordinate my time and take some time off from work.
