Korea tax exam AI glasses cheating claim: runner-up shows his books

On 12 November, the runner-up, Yun Jeong-hu, posted a video on his YouTube channel. He had passed the first round last year, failed the second, and came back this year to finish with 602 points, an average of 75.25. In the video he showed the textbooks, lectures and notes he used. The books are visibly battered from repeated reading. He also solved tax accounting problems on bad debts and bad debt allowances on the spot, explaining his steps without a script or answer sheet.

Yun said he was not boasting. He wrote that he wanted people to stop the baseless attacks on the exam and on licensed professionals, which he said belittle the effort of people who study for it and pass.

What is the investigation into the tax exam doing?

The exam's organiser, the Human Resources Development Service of Korea, has opened a review of A's exam and marking. In a statement on 13 November it said it had found no concrete evidence of cheating. All four invigilators who watched A's two exams reported no smart glasses or other suspicious behaviour. Experts are still reviewing A's essay answers from the second round.

A has hired a lawyer, who said his client will cooperate with the necessary procedures. The Prime Minister's Office said it treats cheating with AI smart glasses as a serious threat to fair opportunity. It promised an inquiry that may include a referral to investigators, and said anyone found cheating will be held responsible under the law.
