If you are happy to just know the minimum required by the regulator, then fine. But some are eager to have superiour knowledge compared to the bare minimum required and prefer not to just learn the questionbank ( they should eliminate that) by heart.
staring at a whiteboard? No, but we had orals, internal exams ( fail and you are a gonner by the way) ,essays, had to explain topics to the whole promotion,... the current requirements are a sad joke.
