I am a senior one student, and I am not good at math. I think you can find a tutor, don't let him give an empty lecture, but tell you some ideas to solve the problem. For some similar problems, we can summarize and classify them, such as adding an auxiliary line to the circle. Or you can concentrate on a topic, not quantity but quality, understand it thoroughly, then filter it in your mind and sum up your experience. You can also exchange learning methods with students who are good at math, listen to how they learn and learn from their good learning methods. But I think the most important thing is to build confidence. Don't think that I just can't learn well, so people will never learn well. I hope you come on, and I will come on! Nothing is impossible as long as you believe in yourself!
