This is not another quiz. It is the real instrument end to end, at real length, under a real clock, so the first time you sit 240 minutes of multiple choice is not on the day that counts.

Rules

• 175 questions in 240 minutes. That is about 82 seconds a question.
• One continuous sitting. There is no pause button and no scheduled break, the same as the real exam.
• The clock starts when you press Begin, not when this page loads, and it runs on wall-clock time. Closing the tab does not stop it.
• One question per screen, with Previous and Next. You may move freely and change any answer until you submit.
• Flag anything you want to come back to. The review panel lists all 175 as answered, unanswered or flagged, and jumps to any of them.
• No feedback until you submit. No correct or incorrect, no explanations, no running score.
• It submits itself at zero. You can also submit early; you will be told how many are unanswered first.
• Pass mark is 67%. Unanswered questions score as wrong, so guess rather than leave blanks.

How the paper is drawn

Questions are drawn fresh each sitting to the published domain weights, never evenly across the pool. Question order and answer order both shuffle, and items you saw in your last two sittings are held back where the pool allows it.

Counts total exactly 175. Where a domain shows a range, which domain gets the spare question is decided at random for each sitting.

Keyboard and touch

Everything works without a mouse. 1–4 or A–D selects an answer. → or N is next, ← or P is previous, F flags, R opens the review panel, Esc closes it. Every target is at least 48 pixels, and nothing needs a drag, a hover or a precise tap.
