Silver way

    I'm going crazy~~!!! These two textbooks really drive me mad!!! 
    First of all, providing the wrong answers. How would part two and part three questions have the same answers?? The answers are ridiculous!!Secondly, there are just 40 questions in the official listening test not 43. What's more, the pictures provided for the map completion and diagram labeling are also awful and make no sense!! I even have to spend more time to figure out the given questions while I practicing the listening tests!! I've never met this kind of problem before! I think that I really buy the wrong books. However, I really do not prefer those textbook in simplify Chinese even though they are much cheaper. I like the books which are published in my country, but why should I confront this dilemma??!! 
   Well, I expect to finish the listening textbook in the middle of March, and had better practice the official test earlier to avoid getting unfamiliar with those questions in the real exam!!!
