1, establish connections, produce associations Any one of the knowledge is not isolated, to learn to link the new knowledge and learned knowledge. This is relatively time-consuming, but it can promote understanding and make the memory more profound. These connections can be the connection of knowledge points within a discipline, or the connection of knowledge points between disciplines, or the connection of interdisciplinary knowledge. Once the knowledge is connected, when you see this knowledge, you can think of another one, and when you remember this one, you basically remember the other one. There are four general laws of association, namely, proximity association, similar association, comparison association, cause and effect association.

2, recollection method: recollection can be regarded as a better way to enhance the memory, before also systematically said. Anything, any knowledge can become your memory object. For example, after class to recall what knowledge points have been taught in class; the end of the day, recall what knowledge has been learned today, what has been done; walk through a road, recall what buildings, stores, forks in the road, and so on.

3, repetition: the root of memory is more repetition than skill (skill is only an auxiliary means). The best way to prevent forgetting what you've learned is to review it before it's too late. According to the forgetting curve, the speed of forgetting is first fast and then slow. As the degree of memory consolidation increases, the number of reviews can be gradually reduced, and the interval can be gradually lengthened. Jealousy in the study after a long time to review, so that the knowledge learned will be forgotten, it is the same as re-learning.
