As far as I understand, "step-by-step approach to teaching" means that questions are ORDERED in such a way that learning will be as good as possible. But shuffle questions mode in this test is on. How is it possible that this quiz nominated for "step-by-step approach to teaching"? What do you think, Giant Snail?
