How it works
- The timer starts when you press Start and runs on our clock. Your answers save as you go, and the exam submits itself when time is up.
- Multiple choice and fill-in answers are marked instantly.
- Written answers and pseudocode are marked by AI against the mark scheme (uses one of your 20 daily AI questions, for students with an unlocked level). You always see the model answer.
