Two: study at ordinary times is to specialize in research, and don't give up easily when encountering problems. When you really can't solve it, ask your classmates or teachers. But you'd better ask the teacher. The teacher has comprehensive knowledge and detailed explanations.
Third, actively participate in extracurricular activities. Play hard in physical education class. But of course you should pay attention to safety. You should combine work and rest.
Four: The most important thing is that you should have your own goals and stick to them. Have confidence in yourself. When encountering difficulties, don't think about how difficult it is. Calm down and think about the solution.
Finally, I wish you success.
