I can only say that whoever buys is unlucky! I am a third-grade English student, and I paid 2200 yuan, which said that I gave two sets of secret questions and then guaranteed the agreement. God, I didn't promise anything. Until you pass the exam, work hard by yourself! Six-day face-to-face teaching is to help you review the content, and I don't want to have any exam skills! I just want to say, is there a complaint department or something? Give me another chance, I won't invest money!
