Whenever I see the certificate on the dormitory wall, I will recall my experience of participating in the quick calculation competition in primary school.

That was when I was in the second grade of primary school.

One day, Ceng Laoshi, a math teacher, announced in class that the school would hold a quick calculation competition for the whole grade. When I got home, I began to practice. According to the rules of the competition, 104 arithmetic problems must be completed in fifteen minutes. Doing something wrong doesn't count. I have practiced my exercise book several times, but I can't meet the requirements and always make mistakes. I can't help but feel discouraged, it's too difficult! At this rate, it is impossible for me to rank. Stop practicing. At this time, my mother came to comfort me: "Xiao Ming, don't lose heart." Practice makes perfect. We can only make progress if we practice a few more times. Moreover, we are not only participating in the competition to win the ranking. "

Mom's right. Don't always think about games, just improve your computing ability. From then on, every day when I came home from school, I gave up the opportunity to watch cartoons and practiced doing problems first. Finish homework every day, give up the opportunity to play video games, and still do problems; My neighbor's children invited me out to play ball on weekends, which is my favorite sport. But I just gritted my teeth and insisted on staying.

"There are many good things to grind." After a period of hard training, my problem-solving speed has really improved, and I can easily complete the answer within the time required by the competition. In order to improve the speed, next, I also let my mother be my coach and referee. I improved some calculation methods and corrected my mistakes. Mom also found a stopwatch to record the time and conducted a "practical exercise" together. After staying up for several nights, my mother once told me that I finished all the questions in five minutes. I can't believe it's true. How I want to take part in the official competition at once!

Waiting and expecting, the quick calculation contest finally came. Although I am a little nervous, I seem to have a very confident feeling when I think that I can finish it easily at ordinary times. After getting the competition questions, I almost held my breath and handed in the papers first.

A few days later, the results of the game came out. It turned out to be the first grade! When I received my prize from my teacher, I felt that I had succeeded this time.

Looking at this hard-won award, I understand a truth: whoever has confidence, hard work and courage at a critical moment will surely succeed.
