Really smart children, their thinking ability far exceeds that of their peers, the learning content is too simple, and the Buddhist character makes them seem to work less hard.

For example, in the lower grades of primary school, children lack attention and detail in doing questions, and are prone to some carelessness, which is normal. However, some children are less likely to make mistakes by brushing questions for a longer period of time, making it easier to get a perfect score.

At this time, purely from the point of view of grades, thinking ability is covered by grades. The results that can truly reflect the thinking ability are, first, the test questions themselves can reflect the thinking ability, and the other is in the same learning input. This makes it very easy for "smart" children to appear in the lower grades of primary school, and their energy is not on learning.

However, with the improvement of learning intensity and difficulty, smart children, their learning dedication has improved, and their academic performance has also improved, such as the second year of junior high school geometry and functions began to change the thinking track, some really smart children, the driving force of learning has also been greatly improved, the second watershed of junior high school is not only the lag of some pseudo-school tyrants, but also the opportunity for some people who like to think about the improvement of children's grades.

而進入高中階段，難度上限的提升，足夠大的區分度，使得即使再聰明的學生，全力以赴，都有提升的空間，小學前1%和前50%努力與不努力差距不大，初中可能只有前1%和前10%努力不努力差距不大，而高中前0.1%與前5%相比，都有極為明顯的差距。

In contrast, fake smart children, the so-called smart performance, like to play games, talk a lot, this is just the cognition of most ordinary people who are not smart, not really smart.

These children don't work hard, that's because they don't know how to learn, they don't have an interest in learning, and they have a different ability to learn.

To make it even funnier, some boys deliberately let themselves pretend not to work hard in order to highlight their intelligence, and they even gathered in groups to laugh at the students who worked hard.
