Different from other types of exams, the most distinctive feature of the IELTS speaking test is its humanity. Unlike the computer-based TOEFL exam, the IELTS speaking test does not entirely depend on the candidate's oral expression ability. A large proportion of the score actually depends more on the candidate's performance on the spot. This on-the-spot performance isn't just about the candidate's condition; many times it also depends on the examiner themselves, communication skills (non-verbal level), and whether the candidate has prepared for the content asked in the exam. Therefore, IELTS speaking is the most unpredictable subject for candidates; there is often a significant difference between the predicted score and the actual score. Thus, we can see that the key is how to effectively capture the examiner's attention and leave a deep impression within these 11 to 14 minutes.
