Interestingly enough the Seed tests are on the tutorial section.
Now,do you think that Squaresoft put it there just as an interactive tutorial to help the player get the basics of the battle system?
Of course not.Would there be no need to make written exams to become a Seed it wouldn´t appear on the tutorial.Thus it is contextual and not absolute.
Also,how can you explain expressions like "Is still unknown" or "Its difficult to determine" on the tutorial?Squaresoft knows everything so either they tell it or keep quiet about the subject if they wanna to surprise us.They made the game after all.It would be as pathethic as if one find "The effect of the triangle button is there but is unknown" on the game manual.
Which means that the tutorial is context sensitive and not an absolute description by Square.
