Learning more problem-solving skills, such as the special value method we often use to fill in the blanks, will help you improve the speed of solving problems. Encounter as many problems as possible, so that you won't panic even when you get to the college entrance examination. Taking this as a breakthrough, it takes a lot of calculation to find out its relationship with XY, but you must do it when you have time. Conic curve has a cheating strategy, an unknown linear equation (if there is K, we must see whether there is K or not, and the number of unknowns should be reduced as much as possible) and the conic curve equation are simultaneous (this is usually found in the first question). Eliminate the unknown X or Y to get an equation about Y or X, and then write the roots and roots with vieta theorem. (The topic of general conic curve is 8 points here. )

At this point, if you don't want to do it, you can skip to the next question. If you have to do it, pay attention to the time and read the questions carefully again. If there are one or two special cases (not curve equations, but various relationships), it takes this as a breakthrough to find out the relationship between it and XY, which requires a lot of calculation, but we must do it when we have time. Don't doubt that you have miscalculated. At this time, you should do it boldly.

Derivative is an important point of function test site, and it can take a week to master derivative. Range and monotonicity are also frequently tested, which is easy to say. There is another scaling method, and the key is to find out where to start. The last question The last question is basically done very little, so you can give up. It depends. If you are an average student, if the question is difficult, you can give up the last question, because usually 24 questions will be more difficult and time-consuming. If you are smart, finish the first question of each question first. The first question is simple.

If your reaction is quick, the premise is that you have done everything right in front of you and you still have time, so you should delve into questions 23 and 24, do the previous questions quickly and correctly, that is, the questions before question 23, and leave enough time for questions 23 and 24. Finally, you should have confidence, motivation and a tough heart. Steps are also important.
