Derivative, as an important part of college entrance examination mathematics, often appears as the last question of college entrance examination, which is generally difficult. For a long time, there has been an idea that the second or third question of the derivative finale may be too difficult, so when the exam is necessary, we can give up the second or third question of the derivative finale and ensure that we get the basic score of the previous question.

If we objectively comment on this concept, we can say that this concept is very pertinent to some extent, but it is also unscientific. Imagine that if you get into the habit of giving up the second or third quiz at the derivative finale, you may lose a lot of points in the exam because of the lower difficulty of the topic, which will make the strategy of "maximizing the total score" ineffective to some extent.

At present, the difficulty of the derivative finale of the college entrance examination tends to be moderate, unlike some simulation questions, which are difficult to control.

Taking the title of derivative finale of the national college entrance examination in 2020 as an example, we can find that this year's national paper derivative test is still based on functional inequality, and the key points are to investigate the selection of zero, the establishment of constants, the nature of functions and so on. The above direction is a routine that often appears in daily exercises and various simulation questions, and it is also the key topic explained in the first edition of The Secret of Derivatives.

It can be said that through the study of school courses, the strengthening of teaching AIDS and the stability of extracurricular exercises, candidates can basically master the above points systematically; Therefore, the theory of "abandoning the finale" is actually not enough training. The best choice for classmates and friends is to practice normally, try to overcome the fear of difficulties, see more questions, and take the initiative to test and solve problems during exams.
