It is difficult to recruit math and science in junior high school in advance.
Mathmatics If you get good grades in primary school, many schools will enroll students in advance and attend their junior high school. Compared with science, junior high school mathematics is more difficult to learn. For science, it is easy to get full marks as long as the corresponding key knowledge is memorized. Mathematics not only needs to recite knowledge points, but also needs to be flexibly applied to various problem solving, and there are many steps to solve problems, many of which require thinking to answer.
