The reason for this is the following:
1 Time-honored network? Station, done earlier, more attentively, updated every year, there will be a notice in the station, a total of more than 2300 questions (this question is still the time period of my exam, they are updated every year, generally it will increase, you should see it yourself), which is more accurate.
Each chapter has a chapter question bank corresponding to it, followed by simulation questions. The software interface is exam-oriented, the mobile phone and the computer can be synchronized, and each question has an answer analysis, which can make time for self-study. It is good to block the answer analysis during the exam and look at the answer and analysis after the exam.
Anyway, go and see for yourself. I think it was very helpful for my exam at that time.
