I have to go on Saturday and Sunday, and the result is only 10 class hours. I study electronics, with many courses and little time. I feel that there are many things promised during publicity, saying that it is group training (such as eloquence), and the result is some simple training, and then I plan to practice it myself. After all, there is only one day when I don't have time to give us group training. Finally, the teacher said, "We'll talk about this later" and "We've talked about this before", but. . . . You know that. Anyway, don't sign up for too many courses, and don't sign up for those who don't focus on business. Of course, as long as you study hard, you can still learn a lot (but why choose to learn everything? I've had enough. It's no use not studying. The above is for your reference.
