Reynie’s suspicion about his ability
When Reynie first learns of the available opportunity for intelligent children, he concludes that he cannot compete with others because he cannot pass the exams. According to Reynie, he is an average student, and the exam needs super-intelligent children to pass. The tests are strange, complicated, and difficult, thus, requiring children with supernatural talents to excel. However, Reynie is persuaded to attempt the tests. Ironically, out of the hundreds undertaking the series of tests, Reynie emerges the best and among the four who excelled to join the genius program sponsored by Mr. Benedict. The reader finds it ironic that a student who doubted his capability at first comes out as the best among all participants.
Dramatic irony

After Reynie gives her part of his pencil, Rhonda promises to help him cheat in the exam. Readers know that Rhonda is not a student because she is part of the examining team. Rhonda wants to test if Reynie can accept cheating in the exam, and that can lead to his automatic disqualification. Reynie refuses to cheat in the exam because he prefers not to use dishonest means. Later, Reynie is shocked when he discovers that Rhonda is part of the test, and he passes when he refuses to cheat.
