▪️ IELTS pretest sets are full mock test materials used before official exams to: 

– trial new question types     – test new topics or formats     – check the difficulty level of questions     – observe how real candidates perform

▪️This is why these sets usually contain 49 listening questions and 46 reading questions, rather than the standard 40.

▪️ These materials are typically written by IELTS test developers and trialed under real exam conditions.

▪️ Many future IELTS questions are recycled or adapted from pretest materials.
