There are four people in the driving test. Did the first three people pass, and the last one must fail? Is there a quota?

Well, although there is no such provision in the regulations, it is conceivable that this is human invigilation, not computer invigilation. If he lets you pass all at once, I don't know what others will think, but it will be reformed soon. If you use infrared invigilation, this will not happen, but the make-up exam will generally let you pass.
