When reviewing for the IELTS examination, students are very conscious with the scores that they get. Their scores indicate how well they have been doing in the IELTS review. Students use their scores to indicate whether their knowledge for the examination is already enough for them to reach their target scores.
Both reading and listening have a 40-item question. When you take practice tests, you may get a score of 30 and not know the equivalent band score of your raw score. For students to have an estimate of their band scores, there is this IELTS Band Score Calculator that we have.
