As we all know, three years of high school in China is the hardest. In senior three, you have to redouble your efforts to get a happy ending. For art candidates, the pressure may be even greater, but in terms of cultural achievements, there must be a study plan. Learn to plan yourself, how to grasp the score and improve the score.
As far as Chinese is concerned, as long as you follow the teacher's rhythm and grasp the most basic things, there will generally be no big gap in Chinese. The key is to master the basics of mathematics, and you don't need to do particularly difficult problems. The basics are good enough for you. Do more questions, problem sea tactics. Everyone should know. Learn to recite words in your spare time and time, and your English will not be too bad.
