Normal learning input should be three percent of primary school, seven percent of junior high school, ten percent of high school, and the corresponding primary school is also three points of difficulty, junior high school is seventy percent of difficulty, and high school is ten percent of difficulty.
However, the existence of extracurricular training and rush has made many families let their children exert 70% of their strength in primary school and 10% of their efforts in junior high school, and obtain the same results, paying far more time than their age group.
If all children put in 30% of their time in primary school, there will be no common high scores, a few children can score 98 out of 100, some children score 95-95, and some children score less than 85.
The reason why there are few "low scores" below 95 points in primary school is that in order to get high scores and full scores, students with 85-95 points spend 70% of their time on training, and those with less than 85 points use 10% of their efforts.
The reason why the scores of some primary school students decline in the second stage of junior high school is that the high scores under the three-point difficulty of primary school are not obtained by three-point investment, but ten points of investment, and after the difficulty rises to seven points, it is difficult to improve the original ten points of investment.
Students with three-point input in primary school can still continue their excellent grades in primary school if their dedication is increased to the corresponding seven points, while students with seven points in primary school need to be promoted to ten points of investment, although they also maintain their grades, but their learning potential no longer exists.
When the difficulty of high school has risen to 10, the level of commitment required has also increased correspondingly, and the junior high school has been very committed to the limit of ability and cannot cope with the difficulty of high school, while the students with 7 points of commitment will be able to cope with the 10 difficulty of high school if they are committed to 10 points.
