About this test happened on October 20th, I‘ve to say that the nervousness indeed made a negative impact for me, especially when I attended the speaking test. I almost couldn’t fluently speak a complete sentence when I first sat in front of the examiner, which, of course, was the first time for me to talk with the real foreigner. So that it was no surprising that the score of my first speaking test was just 4.5, which was a quiet low score for examinees. Besides, the score of other parts of the test were not good as well, e.g. the listening score was just 5.5, which normally, I need to get 6.5 to reach my target. If I have to find a key reason for this failure, I would say that my preparation was obviously not enough. Also, the failure taught me a lesson that, no pain no gain. [ ↓ ]

Here, I will use some words to write these memories down, for myself and also for all of you. Because of the length of this article, I divided it into three parts, named part A and B. The first part (A) is as follows.
