Would it have made a difference to the play experience if, instead of test/skill checks, the GM just decided the exams were too hard and the PC failed?
Yes, that wouldn't be a situation where I would say the GM ought to just declare he failed. And by the same token, the individual steps of the search for the brother, I wouldn't advocate the GM simply declaring he fails to find further clues that lead to him.
