1. Advanced education in schools may lead to students' overconfidence, regardless of basic education. When students' self-esteem is satisfied by higher education, they may neglect to learn some basic learning contents, which are essential for an adult's basic knowledge and social survival.

2. The advanced education of the school is also easy to highlight individual students with outstanding achievements, thus causing psychological obstacles to other students. The advanced education in schools is often aimed at students with high IQ and excellent grades, leaving behind backward students. Students who fail to participate in this avant-garde education are likely to be frustrated by the sense of failure.

3. The advanced education in school may bring students too much psychological pressure. Some students may have excessive tension and anxiety when they pursue success and win the recognition of teachers. For those students who must achieve excellent results under such high pressure, advanced education may bring more burden.

4. Overburden of study time: Studying in advance will make students bear too much pressure in a certain period of time, which may affect the learning effect and students' physical and mental health. Because the information learned is messy, some important information is easy to be ignored or dabbled in, but it has not been deeply understood and understood.

5, affecting the enjoyment and motivation of the learning process: the learning process is too heavy, and when it is too late to complete the learning task, the mechanical, enjoyment and motivation of the learning process will be damaged. If you can't cultivate strong analytical judgment ability, studying ahead of time will lead to students not having enough time to expand their thinking, analyze information and make critical cognition, and only memorize some key points after understanding.

6. Simply restricting and strictly investigating behaviors such as "learning in advance" is likely to be a temporary solution, but it does not solve the essence of its problems. In the final analysis, this is China's talent selection system. Whether it is the senior high school entrance examination or the college entrance examination, it is basically a fraction theory. In this context, it is difficult to change his "profound knowledge".
