In the eastern region, especially in Jiangsu, Shandong and Anhui, the topic of grade six in primary school is very difficult.

Education in Beijing, Shanghai and the western region is relatively backward, and the topics in the sixth grade of primary school are basically basic addition, subtraction, multiplication and division, or a set of formulas.

There is a person who Baidu knows to ask questions. He said that junior high school knowledge has been learned in the fifth grade of primary schools in the eastern region. Tell him this is a primary school topic, and he will become angry from embarrassment and swear. I've been in this situation.

In Jiangsu, Shandong, Anhui and other eastern provinces, learning equations in primary schools, monotonicity in junior middle schools and calculus in senior middle schools have become the norm.

So it still depends on the specific provinces.
