First, learn to remember words, vocabulary is the basis of learning a language well. When remembering words, you should not only move your mouth, but also use your head. In a short time, words may be remembered or forgotten, so be sure to go back and review. Words must be firmly remembered, and they must not be specious, otherwise they will encounter big problems in future use.
Second, learn to do English problems. Practice makes perfect. Only by practicing constantly can English improve continuously. Not only do you have to do a lot of problems, but also carefully analyze your mistakes every time you finish. Doing the problem is not to see what you know, but to find out what you can't do, and then do all this, which can be regarded as achieving the purpose of doing the problem, which is also the key to review.
Third, recognize your weakness, whether it is lack of hearing or reading problems, and so on. And then find the right direction to review. Review is not equal to study. Review means that you already have some knowledge, so it is more efficient to prioritize and review.
