Once you are comfortable with the format, the thing standing between you and a higher band is usually paraphrase. The question sheet says one thing; the recording says the same thing in different words, and often says your keyword somewhere else entirely — as a distractor.
A question about "the cost of the annual membership" will not be answered by the speaker who says "cost". It will be answered by the one who says "you'd pay £60 for the year". Meanwhile the word "cost" will appear in a sentence about something you were not asked about. Keyword hunting walks you straight into it.
Train the two directions separately.
Out of the question. For each question, write one alternative phrasing before you listen. "Difficult to find" becomes "hard to spot", "tricky to locate". "Reduce" becomes "cut", "bring down", "lower". Two seconds per question, and it primes you to hear the meaning instead of the spelling.
Into the answer. After marking a set, take every question you got wrong and find the exact moment in the transcript where the answer was given. Not roughly — exactly. Write the recording's words beside the question's words. That pair is what you are learning.
There is a second, quieter skill here: hearing the turn. Answers often arrive after a signal that a correction or a contrast is coming — actually, in fact, having said that, on second thoughts, whereas. When you hear one, the sentence that follows is likely to matter more than the one before it.
