Don't go. You can take the exam without paying, which is very simple and easy. It is said that you only need to spend 2 hours in class every day for 3 days a week, and then take notes and brush the questions 1 hour. As a result, the class is not so simple. There are many knowledge points to remember, even if you spend three or four hours a day, you can't finish learning them. If you don't give it back now, you will be angry if you don't listen to the rest of the courses.
