Just kidding, hehe. But it's better to write at night. You can do it for three hours in the evening during the holiday. A person writes, controls himself, does not sleep, and makes himself feel that it is a very happy thing to do the topic (see your attitude). If there is a challenge, you will feel a sense of accomplishment when you finish it, and the more you do it, the more you want to do it. Usually you just do it in the self-study class. After school, you sit alone in the classroom and don't take the self-study class. No matter how much you do, whether you can do it or not (the puzzle of 1 takes half an hour to give up, and you don't have to do anything for the other half an hour), never copy it. You should wait until you are completely unsure of them, and then you should fully understand them. Listen carefully in class and concentrate on the highest and highest energy. I think the general problem is still very easy to solve. That's all. What's the problem?
