Apart from being yet another in praise of the PPL Confuser, I can only say the one minor problem I had with my PPL exams was the fact that they are all based around fixed wing and I'm one of the odd types who does the fling wing thing
Such things as stopping distances on various surfaces didn't mean a great deal to me. And I don't foresee me spending much time worrying about operating performance about FL245.
Either way I still passed.
