1. Pay attention and concentrate. As long as you concentrate on your memory and eliminate distractions and external interference, the cerebral cortex will leave a deep and unforgettable memory trace. If you are distracted, your memory efficiency will be greatly reduced.

2. Strong interest. If you are not interested in learning materials and knowledge objects, it will be difficult to remember even if you spend more time.

3. Understand memory. Understanding is the basis of memory. Only what you understand can be firmly and permanently remembered. It is not easy to learn by rote. For important learning content, if we can combine understanding with reciting, the memory effect will be better.

4. Overstudy. That is to say, on the basis of memorizing the learning materials, remember them several times more, so as to achieve the degree of memorizing and memorizing. The best degree of over-learning is 150%.

5. Review in time. The speed of forgetting is fast first and then slow. Strike while the iron is hot for what you have just learned, which is an effective means to strengthen memory traces and prevent forgetting.

6. Always remembering. When studying, constantly trying to recall can correct memory mistakes, make up for omissions, and make the hard-to-remember learning content stronger. When you are free, you can often recall the objects you have remembered in the past to avoid forgetting them.

7. Combine reading, thinking, watching and listening. You can use the functions of language and visual and auditory organs at the same time to strengthen memory and improve memory efficiency, which is much better than a single silent reading.

8. Use a variety of memory methods. According to the situation, flexible use of classified memory, characteristic memory, homophonic memory, argument memory, associative memory, interesting memory, chart memory, shortening memory, compiling outline, taking notes, cards and other memory methods can enhance memory.

9. Grasp the best memory time. Generally speaking, 9 ~ 1 1 in the morning, 3 ~ 4 in the afternoon and 7 ~ 10 in the evening are the best memory time. It is effective to use hard-to-remember learning materials.
