There are probably these reasons:

1. basis. Maybe you were a little lax in your previous courses, and you forgot too much knowledge over time, so you couldn't understand it over time. Because the learning of mathematics needs to be gradual, the consistency of learning before and after is very important.

Methods: Consolidate the foundation, pay attention to review while learning new knowledge, and learn new things by reviewing the old ones (of course, it is most basic to be careful in class and ask more questions).

2. Interest. Not interested in mathematics, even feel annoyed. I have always been good at math, and I am often among the best in my grade. I like math since I was a child, and I like to challenge difficult problems. I think this interest has played a decisive role in my math study.

Solution: Feel the beauty of mathematics, establish and exercise mathematical thinking in life, and happily integrate into mathematics.

Thinking. "Learning without thinking is useless, and thinking without learning is dangerous." Learning mathematics needs to be good at thinking, and the simplest thinking is to draw inferences from others.

Solution: Be good at using hands and brains and think more.

4. read. The accumulation of knowledge is a long process. Reading is not only an accumulation, a relaxation, but also a kind of enjoyment.

Solution: read more math books; Mathematics is a reflection of thinking, and reading some books that can exercise thinking is also a good choice.

5. practice. I have to say that China's exam-oriented education does have some drawbacks, but doing more exercises is indeed the most basic way to improve your grades.

Solution: Do more exercises to consolidate knowledge.

6. Time. Improper time arrangement often delays many things. The same is true of learning. People who are in a hurry can often win the final victory. I believe you can make progress as long as you do it in moderation!

Finally, learning needs to have confidence in yourself, that is, self-confidence. Knowledge is the capital of self-confidence, and self-confidence can better harvest knowledge.

Of course, if you want to learn mathematics well, you should not only establish mathematical thinking and think more, but also make it clear that only your own efforts can open the door to success!
