Start Your Engines: The Chūnin Exam Begins!

is episode 24 of the original Naruto anime.

Synopsis
At the beginning of the episode, Ibiki Morino appeared and told everyone to find their seats. Ibiki announced that the Chūnin exams would start with a written test, and called out the rules: No questions, and no cheating. Ibiki also informed that the team's score would be added up in the end to see whose team would pass. There were various Chūnin on the ends of the room watching the genin to see if they were cheating. If they were caught cheating five times, not only was the genin caught five times disqualified, but so was the rest of the team. Eventually everyone, except Naruto, found out that in order to pass, they had to cheat. They then used their own ways to subtly cheat.
