To improve learning efficiency, we must first learn to control our will. Whether you are listening to a class or reading, you should concentrate on it, and don't let all kinds of distractions disturb your thoughts and think seriously. My home is opposite the ballroom. At night, the sound of orchestral music is endless, and parents are worried that it will affect their studies. But as long as I sit at my desk, I can turn a deaf ear to all kinds of noise. Some students don't pay attention to the lecture in class, and spend several times after class to understand and digest; Some students are in high spirits when studying by themselves. Hours passed, but they didn't know what they had gained. For these students, if they want to study well, they must first form good habits: they must concentrate on their studies, devote themselves wholeheartedly, and concentrate on their studies for two hours. Sometimes it is more effective than studying casually for four hours.

Secondly, we should pay special attention to improving the speed of doing problems and exercising the agility of thinking. This is not only to improve learning efficiency, but also to meet the needs of college entrance examination practice. Every minute counts, and the topic that can be completed in two hours will never be delayed to three hours. I would rather spend the remaining hour for rest and entertainment than form the bad habit of procrastination and fatigue. When preparing for the math competition in high school, I found a lot of exercises to do by myself, and I wrote down the time I spent in my exercise book every time I finished. The purpose is to test my proficiency and train myself to meet the time requirements of the official competition. I participated in the national winter math camp. We know that every time there is a college entrance examination, there are always candidates who feel that time is not enough. Therefore, we should strengthen the training of problem-solving speed.

Similarly, we should give full play to our subjective initiative in learning. From the surface to the inside, from the superficial to the deep, don't make simple repetitions, don't spend a lot of time doing simple exercises, and don't engage in so-called "sea tactics." Instead, we should grasp the key points and difficulties, draw inferences from others and avoid analogy.

Correctly understanding the laws of memory and forgetting is also an important way to improve learning efficiency. In high school, many things need to be memorized, such as English words, ancient Chinese, mathematical formulas, theorems and so on. Some students always shout "can't remember", one of the important reasons is that they don't know the rules and methods of memory. From the psychological point of view, memorization can be divided into unconscious memorization and conscious memorization. Systematic knowledge, especially systematic scientific knowledge, can never be mastered by "unconscious rote learning". Having a clear purpose beforehand and working hard in the process is "consciously recording". In other words, reading the text twice attentively, consciously and actively is much more memorable than reading the text ten times casually. Rote memorization cannot be done once and for all, and the basic condition for consolidating rote memorization is review. You should know that the law of forgetting is fast first and then slow. After memorizing, the speed of forgetting was very fast at first, and then the speed slowed down. Experience shows that after remembering a material, the amount of forgetting in the first five days must be greater than that in the last five days. According to this law, we can completely resist forgetting. Is to review more times than before, so as to get twice the result with half the effort. Just like facing a dam, we should reinforce it in time when it leaks, instead of waiting for it to collapse and rebuild it. To prevent forgetting, a rough review is enough, but to restore forgotten memories, a lot of work is needed.
