Are you studying f(x) at this time of senior one? Just some properties of equations or something. You should learn to draw, and draw by yourself while reciting the property theorem. Is there a trigonometric function at this time? Trigonometric functions memorize formulas, so when I do the problem, I just take it casually without thinking and try it one by one. Many reference books will list all kinds of questions. The best way is to preview before class, do some basic exercises, do everything you can and remember everything you can't do. Then listen carefully in class, and many problems that you can't do will be very useful at this time. Finally, the teacher should review well and understand the questions thoroughly after speaking, so that the next time he sees this kind of questions, he can start writing immediately. You really need to work hard to get high marks. The better the grades, the greater the interest, which is positively related. I often get full marks in high school, my own experience. Remember, you must work hard?
