Personal real experience, the system of storing examination classes has been very mature, in order to make up for the lack. I couldn't do it properly at that time. They have an independent project, which really helped me improve my test. It is still recommended to apply for the ace class during the interview. The service has nothing to say. Mr. Lao Hu, the inspector, and Mr. Xiao Yang, the head teacher, are both responsible and are both graduate students in your school. The quality is relatively high. After customs clearance, all the expenses are more than 20 thousand. You can refer to it I'm glad you can accept my answer.
