The IELTS test is divided into four parts. There are four sets of IELTS real questions, because the IELTS test is divided into four parts: listening, reading, writing and speaking. Each part has two sets of questions, which are called "academic courses" and "training courses". Therefore, a set of IELTS real questions has four sets of questions, corresponding to two sets of questions in four parts respectively. This setting can help candidates fully understand the questions and difficulties of the IELTS test and provide targeted guidance for preparing for the exam.
