How to say hello to classmates?

When students enter junior high school, the courses they study are very different from those in primary school. Students will be exposed to many new learning subjects. The new courses in junior high school include history, geography, physics, chemistry and biology, and some subjects will be changed in each grade.

Chinese, mathematics, English, morality and rule of law will run through junior high school for three years.

Geography, biology and history will be offered in grade seven, physics in grade eight and chemistry in grade nine. The reason why junior high school courses are arranged in this way is mainly to consider students' acceptance ability.

The first-year students who have just entered junior high school are also influenced by the learning thoughts and habits of primary schools, so junior high school is not suitable for offering theoretical subjects such as physics and chemistry, and needs junior high school mathematics knowledge as a foreshadowing.

Extended data:

Primary school has six classes every day, and the students in Class Six need a lot of time. When they enter junior high school, the number of classes a day will increase to 7. Many students are exposed to more complicated basic knowledge in junior high school, such as the language of classical Chinese, mathematics algebra and geometry, systematic English learning and so on. Everyone needs to pay attention to students' learning and thinking in class.

You can't listen and play as you did in elementary school. In junior high school, some knowledge teachers only explain it once, instead of repeating it several times like primary school. They won't review everything before the exam.

Therefore, compared with primary schools, junior high schools have made a qualitative leap in learning courses, learning contents and learning methods.
