I did…I want to say about 35 hours?

And I also supplemented with a g25 wheel/pedal set and ETS2.
Which helped more than you might expect (gear positions, clutch control, dealing with other traffic, blind spots)

G25 has been lent out to multiple friends to do the same thing too, so definitely paid for itself.

Theory, once you’re paying attention to the road in general, isn’t too bad at all. I paid about a fiver for month’s access to a revision website, which had the material, and almost identical hazard perception clips.
