University exams? Aren't there nationwide exams (and they even publish nationwide rating of the student) in Japan? I thought that the results of these exams can be used in order to be accepted into any university, without having to pass that university's entrance exams.
I mean, if I want to get into a university A, B, or C (depending on the number of competitors) that require Mathematics and Physics scores, in my country I'd just pass one Mathematics exam, one Physics exam, then send my papers and exam score to all those three universities and then go to one of those which accept my scores.
I don't need to go to each of these three universities and attend 2 exams in each (6 exams in a row) in order to be accepted.
