After all, calculus is very different from middle school mathematics. Calculus is not so much advanced mathematics,

More precisely, she is a mathematical method-a method of analyzing and solving problems, which was developed by Newton and other masters.

3, a certain proportion of students, after entering high school trigonometry and solid geometry, began to struggle-it took a lot of energy to learn well, just because of the aforementioned [1], there were differences in their minds. Mathematics is an ability [not equal to intelligence].

4. When you get to the university, the difficulty in this aspect may escalate.

Statistics show that no matter how good a teacher is, facing the whole freshman, it is difficult to ensure that all his students can get a better level of advanced mathematics learning. The supplement after "3+4" comes from the research results of famous teachers' teaching. I believe that not everyone can learn advanced mathematics well. For some liberal arts students, it may be more difficult.

So if you want to learn linear algebra and calculus well, you have to redouble your efforts, starting with 1 I hope you succeed. But if you invest a lot, you still can't do it, and don't be forced. Because 1, 2,3,4. There are indeed differences, even great differences, between human brains.
