How to answer

• Questions appear one at a time. Use the palette on the right, or the section tabs, to move around.
• Under each answer box you can type, dictate with the mic, or photograph what you wrote on paper.
• Wrote a whole section by hand? Scan it with any mobile scanner app and upload it against that section — you only scan the parts you did on paper.
• "Save & Next" records your answer. "Mark for Review" flags a question to come back to.
• Your answers save themselves as you go, so a closed tab or a lost connection costs you nothing.
• The clock is held on our servers and keeps running once started — exactly like the real exam.
