Driving is one of the most complex everyday occupations there is. It asks you to scan, predict, decide, and act, all at once, while the scene keeps moving. Plenty of learners know the rules on paper and still freeze at a live intersection, because reading a page is nothing like reading a road.
So this is deliberately not a written test. Every scenario gives you the picture first, from above and from the driver's seat, then asks what you would do. Hazard rounds ask you to find the danger before you choose. That is the skill that transfers to the car.
Play it in short bursts. Getting one wrong here is free, and the explanation tells you the rule and where it comes from.
