In the examination room of the senior high school entrance examination, candidates are prone to make two mistakes. First, due to excessive nervousness, problems that could have been done easily will not be done. Jump from this question to that question, and then jump from that question to other questions. A lot of time was wasted, but there were not many questions. The second is from the beginning to the end. I don't know how to give up when I encounter problems that I can't do. I spend too much time on one topic and have no time to do the next one.
In the examination room, candidates should break through one topic after another in the order from top to bottom and from shallow to deep, and learn to give up when encountering problems that can't be done. They should first do those questions that take less time and score quickly, and then, when time permits, chew on those off-topic, strange questions and difficult problems.
