The official paper is worth 120 marks. This mock holds 116, because we only use questions we have checked and they don't fill every section of the official paper exactly. Your score is worked out of the marks in the questions you sit, so a perfect paper scores 100%.
Before you start
We do not yet have enough questions in this subject to fill every section of the real paper, so some sections are shorter and the marks are adjusted to match. Sit it anyway to practise pacing.
What this mock covers
- Section A - Multiple choice: 36 multiple-choice questions, auto-marked when you submit.
- Section B - Short and extended response: 27 short-answer questions (80 marks), self-marked against a model answer.
