The JP exam result out

I got 95/100 in Japanese Midtern Exam result, I corrected all my errors. And now I am mourning my grade. I began to review the recent actions, I did not pre-studied Japanese textbook, it is my fault. So I think I should pre-studied the textbook on Tuesday and Sunday. In this way, I will get 100 in big exam agian. My Mom thinks that I don't need such a persistence in Japaness, but I will think of how hard I learned for Chinese. How much time and effort I have spent in Chinese, all same in Japanese and German. Soon I will also write a diary in Japanese and German to replace traditional Chinese. All I did just for proving a fact. Even though it sounds childish, I still insist to the last second.
