1. Buy a small alarm clock to keep your life regular. Since you like surfing the Internet, you should make it regular, such as getting up for a few days in the morning, sleeping at night and watching Chinese and English in the morning. It is best to surf the internet on weekends and holidays, and exercise restraint at other times. Don't indulge our desires and do whatever we want.

2. study the real questions over the years and do them repeatedly, not to ask you to recite the questions, but to observe where you like to take the test through the real questions. Some knowledge points in the book can only be tested in small questions for n years. Don't waste time and small probability events. The usual simulation questions can't reach this point. How difficult is the real question? Grasp the basic questions, the basic questions will not lose points, so the math scores in the exam will not be very low.

3. Think more about cost performance. Mathematics does not drag its feet, maximize its strong discipline and strive for full marks. After all, the exam is about the total score.
