Some students' grades plummeted, while others "rose steadily". The big gap between children's grades is nothing more than whether their learning status is good or not. The influence of the external learning environment and the change of learning style all affect their own state.
For example, learning in junior high school is very easy. Those students who studied well before are clever, but they don't work hard. The knowledge of high school is much more than that of junior high school, and it is also very difficult. Due to the increase of learning content, the speed of teachers' class will also be accelerated, and they will relax such learning, and their grades will naturally drop slowly and sharply. Students can't adapt to sudden changes, and their mentality will get worse, which will lead to their failure to keep up with their studies and finally give up.
How to deal with:
Don't give up on yourself, there is no problem that can't be solved. Talk to teachers more, ask children who study well, use their brains and exercise more, and you will find that learning is not as difficult as you think. On one's road to success, self-confidence is the most basic. No matter what happens, don't give up on yourself, so that you have a chance to become a leader.
