Adjust your state of mind, avoid being impatient and rash, carefully examine the questions, answer the questions in the order of easy before difficult, and gradually overcome them slowly and steadily. Do your homework first after you go home, and then preview and review. Preview and review actually don't take up too much time, and finally reach a cycle of conscience. You also said that there has been a lot of homework recently. Why is this? The mid-term exam is just around the corner, and the mid-term exam has passed, but this semester is coming to an end, so it will increase the amount of homework. Don't worry about it. This is a normal process. Every school is like this now. After getting through it, it's summer vacation. In addition, if you feel unwell, you should go to the hospital for examination as soon as possible. Don't worry, you have been checked in the hospital.
