The biggest mistake of many upper-intermediate students is that they cannot correctly analyze their own strength, pursue too much difficulty, and ignore the basics, and lose a lot of points on the avoidable easy-to-make questions.
The level of the high school entrance examination is still dominated by basic questions, even the most difficult mathematics is no exception, a small number of finale questions are just to distinguish the head of the top students, but it is not the focus of the high school entrance examination, the main distinguishing question type of the high school entrance examination, lies in the difficulty of being able to achieve five or five streams, which is the key to whether the middle and upper class students can go ashore.
The mistakes of these mid-range questions often make students feel that they can, but they are not attentive to the questions, and they can be corrected and improved next time with a little attention, such as the simplest rational number calculations, polynomial calculations, inequality calculations and fractional calculations, probability and statistics, etc., the essence of the errors often occurs, not simply careless, but not enough number sense.
The problems beyond the scope of their ability are suitable for those students who have no challenge in the mid-range questions, who spend a long time not understanding or seem to understand, and only understand even the same kind of questions can not be made immediately, this kind of improvement is obviously decoupled from their actual ability, which can neither improve their ability nor improve their thinking, but ignores the consolidation of basic ability.
Many famous teachers will focus on difficult problems, and even the explanation of strange questions, many of the skills used in the topic are very different, which makes people feel bright, but it is not a normal thinking derivation based on knowledge points, but it can enhance the attraction and attention, for middle school students, this kind of topic does not have much learning effect.
In the limited time in the examination room, the eugenics are striving for less deductions, and the scoring rate of the finale question is important, while the middle and upper class students are pursuing more scores, and the medium questions with higher scores and higher discrimination are more important.
