I hope I can help you.
Memorizing some fixed phrases, personally, I think it is completely unnecessary to have a vocabulary book or something. You can do some real test papers to practice writing, find out your relative weaknesses and strengthen them.
Listening: Listen repeatedly, first to see how much you can understand, then listen to the original text again, see what you can't understand, and listen again without looking at the original text.
Multiple choice questions: word meaning discrimination and fixed collocation. Just find a fixed phrase and write it down and recite it (in fact, people who are good at English in high school don't have to worry about A-level at all). You can sort out the wrong questions and then read them repeatedly to cultivate a sense of language. Sometimes, doing English questions depends on the sense of language. With a strong sense of language, not only can multiple-choice questions be done with confidence, but the odds of cloze and reading comprehension will be much greater. .
Cloze and reading comprehension: you can do one article every day. After writing every article, you should find out why you made mistakes.
Composition: You can find some composition templates and recite some. Of course, wonderful sentences are also essential, and generally good sentences can add points to your article.
