I go to high school! I feel that high school mathematics is a bit difficult to learn, especially the algebra parts such as functions and series ... Who can help me find ways to improve my grades?
In fact, when the topic comes out, it is to test those key points. You have to find out the difficult and representative topics, whether you do it yourself or ask the teacher, you have to understand them, so that you can draw inferences from others and have a routine when you encounter similar topics. If you really don't have the patience to persist, consider this question as your college entrance examination question. You do the college entrance examination, you will get it, and you will get the score. Will you still have no passion?
