Dr. Zhang is super rubbish. Where did I sign up? What was the result? Guess what? When I first signed up, I said there were many courses. As a result, Nima always gave us lessons for less than five days, and then said that there would be questions before the exam. There was nothing before the exam. In fact, when did dr. zhang call me and say that he could continue to choose other flights and pay 2000 yuan for face-to-face teaching? Why do I have to pay 2000 yuan? Damn Dr. Zhang, Dr. Zhang is a liar. Five of us signed up for Chengyang Hospital. In fact, only one colleague passed, and the colleague who passed was also a graduate student. I advise you not to sign up, anyone who signs up will be fooled. Dr. Zhang is a liar.
