Ruixing's new employees failed the induction training exam and then went to retraining. In this case, you can only take the exam again until you pass. The company has regulations.

If you don't go through the company, you won't enter. Therefore, you can only retrain and take the exam again, so that you can pass the exam. If you fail all the time, there is nothing you can do but say that you will fail this course.
