All keys

Built for self-marking

More useful than a bare answer table

Grouped the way you test

Answers are split by reading passage or listening part, so you can mark one section at a time.

Hide, then reveal

Turn on Hide answers and tap each one as you check it, so you never see the next answer too early.

Score and band estimate

Tick the answers you got right to see your raw score out of 40 and the approximate band it maps to.

Method

How to use an answer key properly

An answer key only improves your band if you use it to find why you lost marks. This is the routine we recommend.

  1. 1

    Sit the full test under real timing

    60 minutes for all three Reading passages. For Listening, play each recording once and don’t pause it.

  2. 2

    Mark strictly, the way an examiner would

    Spelling mistakes and going over the word limit both cost the mark, even when you understood the answer.

  3. 3

    Find the evidence for every wrong answer

    Go back to the passage or recording and locate the exact line that gives the answer. Doing this every time is what builds speed for the real exam.
