The most important thing in junior high school learning is to let most students understand what they learn, focusing on the popularization of knowledge, while high school learning is to let students who have no thinking ability and only brush questions not understand, so as to select students with strong thinking ability.
The difficulty of the high school entrance examination is more reflected in the diversion, rather than the selection, so there is no need to have too many problems made by only 5% and 10% of the students, most of the questions are made by most students, so that students are willing to learn, and a small number of questions are not done by half of the children, so as to achieve the purpose of five or five streams.
Fewer questions, only a small number of people can do it, but it can also reach 20%-30%, and select key high school students, but this difficulty can no longer be subdivided into Xueba Xueshen and ordinary eugenics, but only to compete for the meticulousness of the questions, so it is inevitable to reorder the grades of high school.
In the case of taking into account the learning ability of the last 50% of students, it is not too difficult to complete the three-stage stratification, so a large number of excellent students have similar grades and high scores.
The main difficulty of each major subject is reflected in mathematics and English, and other subjects, especially physics and chemistry, are less difficult, almost only examining basic concepts, and the purpose is not to set the difficulty for selection, but to make most children understand.
The high school is a selection, so from the middle school entrance examination to the first year of high school, in just half a semester, there are many high-scoring candidates whose grades have fallen, and the change of track is the main reason, especially in mathematics, physics and chemistry and other science subjects, it is very common for half of the high-score full score to not be tested. There are fewer detailed questions, and more questions are the main reason for the test.
