1. Understanding memory. Understanding is the basis of memory. Understanding memory takes a short time and is effective.

2. Interest memory. By making up stories. Play games. Use formulas, homophony and other methods to make boring things more vivid.

3. Associative memory. Use proximity associations, relational associations, and contrast associations for memory.

4. Repeated memory. The law of forgetting is fast first and then slow. Therefore, after mastering it, you need to keep memorizing it over and over again.

5. Collaborative memory. In the memory process, the hands, brain, mouth, ears and other factors are involved at the same time, and the effect will be better.

6. Systematic summary memory. Based on the analysis of materials, use lists and outlines to organize and systematize knowledge. What's more important is to memorize it over and over again.

Additional notes:

(1) Remember important things at the beginning and end. If you are giving a speech, you should tell everyone the important things in advance and emphasize them at the end.

(2) To memorize large-length materials, you can use segmented memory method, so that each paragraph has a beginning and an end, artificially creating conditions for improving memory.

(3) If you memorize several nouns or big questions at one time, you can change their order. Change the beginning and end every time you memorize them, and distribute the review effort evenly.

(4) Organize the memorization materials reasonably and try to make the adjacent learning content completely different to prevent the occurrence of inhibition. For example, if you have just finished studying history, do not study Chinese to reduce the interaction between materials.

(5) Arrange time reasonably. When you get up in the morning, you are not affected by proactive inhibition, and when you go to bed after studying in the evening, you are not affected by retroactive inhibition. These two "golden times" cannot be missed, and you can use them to memorize more difficult materials. Furthermore, when studying for a long time, you need to take a break in the middle, preferably 10-15 minutes. This increases the number of beginnings and endings.

In short, making full use of the beginning and the end will allow you to achieve significant memory effects in the same time and with the same energy.
