All problems are FFT in every division. Change my mind.

I think there's something wrong with the test data of Gold P2, can someone who got AC on that reply to this comment.

UPD: The test data was indeed wrong and the submissions were rejudged.

    I wouldn't consider this cheating but you're walking a fine line so I'd be careful. Anyways, I hope you get your problem solved!

    EDIT: Glad the test cases were fixed.

    Wait there was something wrong with the Gold Problem 2 test data? I thought it was only platinum problem 2? Also, who announced that the test data was wrong and when was it rejudged?

    Edit: Noobita answered my question already: it was early on in the competition and the grading machine had trouble with whitespace. Thanks again Noobita.

Wouldn't the fact that the contest is open the entire weekend allow for cheating if you create a fake account and read the problems and then once you solve them confidently log into your main and start the test? How does USACO deal with this?

    Perhaps the US competitors must do the test in a certain hour or under the supervision of someone. Coordinators trusting in their competitors is a risky bet (perhaps unfair for honest participants)

      US competitors take the exam the same way everybody else does. There aren't any special procedures.

        My perfect world idea is that competitors which can solve the problems obtaining the required score in a weekend, are sufficiently proud of themselves for cheating.
