To tell the truth, it's useless to study in Zhonggong.com, and it's useless to sign up for a class. If you don't know how to do the problem, or need someone to urge you to study, it's not bad to take a class. Last year, I attended the last class in Zhonggong.com. As a result, I didn't get any questions. There are only two days of study, and the tuition is only a few hundred dollars. There is no doubt about it. This civil service exam is not our usual exam, and the topics are limited.
