How to Use This Answer Key

Listen to the full recording once under timed conditions before checking this key, since the real IELTS Listening test only plays each recording once. For any question you got wrong, replay just that section and listen for the specific word or phrase that gives the answer, paying close attention to spelling and word limits (for example “ONE WORD ONLY”), since these are common ways marks are lost even when the answer is understood correctly.
