Read before you begin

• Duration is 20 minutes. The test submits automatically when the timer ends. You can move freely between sections.
• Each correct answer earns +2; each wrong answer deducts −0.5. Unattempted questions score 0.
• Use the palette to jump between questions. Colours show status: answered not answered marked for review.
• "Mark for review" does not affect scoring — an answered question marked for review is still evaluated.
• You can change or clear a response any time before submitting.
