After Harry and Ron had thoroughly mocked Cedric, they told him the first layer of the Golden Egg's secret. As for whether the people from Nanyang Magic School could unravel the rest, that would be up to them.
In Harry and the others' view, though, once they got past the first layer, the next three became much easier all at once.
In fact, the first layer could not really be called difficult. It had simply exploited a blind spot, hiding the secret precisely where people would not think to look.
All anyone could say was that the people on the Tournament Committee who had cooked up the clues were a bunch of sneaky bastards. You could not even find grounds to complain about their reasoning. If asked, they would simply say, "The puzzle we designed was clearly so simple. Whose fault was it that you couldn't think of the answer?"
With the first layer solved, the second would be much easier.
But if the little dragons hatched from Nanyang Magic School's Golden Egg happened to be two particularly rare species-a very likely possibility-and none of the school's professors and students on this trip happened to specialize in fantastic beasts-also a very likely possibility...
Then they would have no one else to blame if they could not get past the second stage.
As for getting past the second stage only to be stuck on the runes in the third, Hermione, at least, thought that was unlikely. She had looked up information on Nanyang Magic School's professors too. They were all outstanding wizards.

If they really did not know runes and could not decipher the
