The IELTS vocabulary depends on how many points you want to test, 5 -5.5 points, 4,500-5,000 words are enough, 6.5 points, 6,000-8,000 words are enough, and more. Grammar, you can make high school grammar solid and enough, and read more grammar books in your high school. Textbook: Cambridge IELTS 4-8 must be bought (1-3 can be bought, the old version has been changed, R articles can be widely read, and you can buy it or not. In addition, I read many world-famous magazines with rich vocabulary, such as Time Weekly, British Guardian, World Geography Magazine, Natural Science and Economic Times. Listen to BBC, VOA, CCTV9, listen to this 2 (extensive reading, the scene inside is very similar to IELTS listening test, very useful), and choose a set of Cambridge real questions for follow-up exercises until you can write it down. The composition can be bought for ten days. Many people use it, avoid reciting model sentences and practice and write more by themselves. If you use the model essay too much, it may be considered plagiarism, or the IELTS composition will not exceed 5 points. If you speak oral English, you can do it together when you do listening and reading exercises. For those who don't know about exams, you can read Lu Wang's quip. Don't recite, you are using it, and you won't get good grades if you recite it. Besides, there are grammatical mistakes in the book, so don't do it. You can look at the topics predicted on the IELTS-related websites, be prepared and master them flexibly.
