1, personal work efficiency is not high. When I was a child, I liked to move more and basically moved less. This situation will lead to too slow homework, whether it is math or other things. The solution is to overcome the problem of "movement". Experts have also found many methods, but everyone has different effects. It is feasible to increase interest in learning.

2, partial subjects, different preferences for various subjects, for example, I have no good impression on mathematics, and I am a little bored, which leads to laziness and inattention when writing mathematics. Targeted measures: communicate with students with good math scores in the early stage, and under the guidance of teachers, do intensive training according to their own weaknesses. Once your grades have been significantly improved, your self-esteem and self-confidence will no longer make you "biased".

3. I can't remember the formula, and I don't have a deep understanding of the formula and theorem, which reflects the result of a single subject of mathematics. Representing the phenomenon is subjective or hard work, but I can't do anything, and my grades are in the middle. The solution is: don't memorize formulas, theorems, axioms, etc. But on the basis of understanding, so as to play the role of "practice makes perfect"

Of course, there are many individual reasons, which are not listed here. In the final analysis, we should be interested, diligent in thinking, willing to work hard and have a good method. As the grades improve, the speed of writing homework will also increase.

Remember: if you can't learn something overnight, you must follow the law of "step by step"
