How to Use This Answer Key

Mark your attempt against this key only after finishing all three passages within 60 minutes, since partial checking undermines the timing practice needed before the real test. For incorrect answers, re-read only the relevant few lines of the passage rather than the whole section, to build the targeted-scanning skill IELTS Reading actually tests.
