Maybe it is just the matter of personal, inborn skills. Maybe it is more the case of how much effort we give into the whole venture. Some people need for example just one attempt to pass an important exam, for example the theory test for the driving license. Other people for instance need even several attempts to pass their theory test. Never there is a situation that something comes very easy to one, without his effort or something on the shape of it. You need to study in order to pass the theory test. Of course there always are some examples that would stay out of the group. For instance the case of Peter, who managed to complete the whole driving instructor training without attempting a single meeting. Zero hours of lectures was just enough for him to be at the second place of the list and to get through the driving instructor training harmlessly. There was just a mistake made consequently by the lecturer, who kept on mixing two similar names. He is not a kind of person that needs several attempts to pass something. I am, unfortunately. I needed seven attempts to get through my theory test successfully.
