Mathematics with poor memory
Chinese nouns. Can you clearly distinguish between fractional words and verbs? You can read the Chinese definition first. Sentence patterns are regular, only a few are fixed. Just remember them. As for math, I am not very good either, but there is only one way to learn math well. Do a lot of problems, and then you will have an idea when you see the problems. If you want to improve your memory, you can only repeat it and keep it.
