Focus on IELTS When you learn a foreign language, there will be mistakes (particularly in the beginning). Increasing our knowledge of the target language will reduce errors. Using the right language in the IELTS test is one of the greatest strengths of candidates because the accuracy of their writing is a key factor. There is a series of IELTS-specific books, published at intermediate and advanced levels, which can help learners address these issues. The method of teaching the correction of common mistakes in English is commonly presented in these books in the form of a few correct and incorrect questions before explaining the relevant point in detail. Finally, students are given a number of exercises to better fit the content for language learners. Answer key All exercises are also placed at the end of the book.
