Junior high school is compulsory education, the focus is on popularizing knowledge rather than selection, and the only slightly difficult subjects are mathematics and English.
Whether it is the two-level differentiation of the second year of junior high school, or the three days of junior high school, it is just a three-stage stratification of the superior, the middle and the poor, whether the composition of the eugenics is a scholar, a quasi-scholar or a pseudo-scholar, at the level of junior high school, it is not possible to distinguish in grades, and there is no need to distinguish, the real selection is set in high school, junior high school does not need to divert out children who lack thinking ability, but work hard, but only need to screen students who do not have the willingness to learn.
The difficulty of physical chemistry in junior high school is greatly reduced, even middle school students can achieve better results, the score difference in language and politics is not large, although mathematics is two-level differentiation, but the phenomenon of high scores is also extremely common, although most of the high scores have a lot of water, relying on continuous training and memory models, rather than using thinking ability to solve problems, and English subjects related to devotion are easier to get high scores through time investment.
After entering high school, the difficulty of all subjects increases, especially physics and chemistry, the steep slope effect is obvious, and many junior high school science thinking is average, but through time investment and training to obtain high scores, the performance of mathematics, physics and chemistry in the three subjects of mathematics, physics and chemistry has declined in an all-round way.
The simple science masters in high school have been greatly reduced, under the condition that science can be learned well, English has become the second roadblock, science is good English is not good, the two groups are particularly obvious, one is that the foundation of township students is not solid, primary school and junior high school investment is insufficient, mathematics, physics and chemistry into high school has no impact, but English has a great impact, and the second is that some boys will spend their English learning time on learning mathematics, physics and chemistry.
