How it works

• Move freely between questions, mark them for review and change answers until you submit.
• The clock runs until you submit. When time is up, your answers are submitted.
• Pause any time — continue later here or in the app with the time you had left.
• You won't see right or wrong while you answer.
• After you submit: your score, rank, the correct answers and explanations.
• A submitted attempt is final and cannot be changed.
• Wrong answers lose marks (negative marking).
• XP is given once; a retake earns more only if you beat your best score.
