What are the ways to supplement learning?

Although it is inappropriate to cram in studying, sometimes it is inevitable that you will have such an experience. Here I will talk about your own method of cramming in studying. If you are a student below high school, you can use your Read the reference book carefully and leave a general impression. Then find relevant exercises to practice, and return to the reference book to study the knowledge points you are unfamiliar with until you have mastered them. This can ensure that your exam will not be a problem, but there are shortcomings in doing so: you forget it quickly. If you are a high school student, a large number of exercises are inevitable, but high school knowledge lies in understanding. It is impossible to complete it in a short time, so do it step by step and see how much you can complete. The above is not a long-term solution. Keep your feet on the ground at ordinary times. This is the true meaning of learning, goodluck.
