The design of IELTS writing answer sheet is very standard. If ordinary people write normally, there will be 9- 1 1 words in one line, so writing 15 will produce 150 words. But we are usually used to writing in western languages, that is, there is a blank line between paragraphs, so we may have to write a total of 20 lines. The first page of the answer sheet is 10, and the second page is 20 lines, that is, the length of the article should be written to one and a half pages, so that the examiner will not think that you are short of words.
