Driving Test Failure

This is mainly just a bit of a rant, so apologies before hand.

So my gf's son (18), just failed his driving test. I don't know the full details right now as I'm at work. I do know that he got 3 minors, and failed. This was because the driving test instructor had to put the brakes on, due to an oncoming speeding car appearing while he attempted to pass a stationary van.

My gf messaged to say that his driving instructor could tell the test instructor did not want to fail him. Personally I think that's a ridiculous and pointless thing to say.

The worst part, and I know all new drivers are in the same boat, the lad has waited since I think Jan/Feb to do this test. Now he has to wait until the next earliest date in our area, which is January! Mental.

I know the rules changed for booking recently, and I think the only way to get one earlier is through cancellation, is this right?
