How to Use This Answer Key

Complete all four parts of the recording in one sitting before opening this key, since Listening tests the ability to keep pace with natural speech, not just isolated words. When reviewing a wrong answer, check whether the issue was losing track of the recording or simply misspelling a correct word that was heard — spelling accounts for a surprising share of lost marks.
