Charging situation
Fees for training courses vary, such as online courses, which generally range from 1000 to more than 3,000, depending on the length of study. Face-to-face training costs range from 2000 to 8000. According to the class type you apply for, there are some general training classes, some intensive classes and some gold medal lecturer classes. There are many names anyway.
Audition suggestion
It is recommended to audition before registering. If what the teacher said is close to the exam and teaching practice, it should be said that it is not bad. If everything he says is scripted, it's no different to learn or not to learn.
