A candidate who came first in South Korea's certified tax accountancy exam has admitted cheating by using a miniature camera, mobile phone and AI tools.
Han Won-seok confessed in a video on the YouTube account of his lawyer, Lee Don-Ho, adding that he had confessed to the Seoul Metropolitan Police Agency and offered details on how he cheated.
The 34-year-old scored 397.5 out of 400 points in the first round, getting just one of 160 questions wrong, which initially raised suspicions and sparked online speculation.
Standardised national tests play an outsized role in career trajectories for South Koreans, making their results - and efforts to unduly inflate those results - of great importance.
"I cheated in both the first and second rounds of the tax account exam by using electronic devices and generative AI," Han said in the video published on Sunday.
"I used a microcamera to photograph the test questions and sent them to an AI then checked my answers on my smartphone to commit the cheating."
When accusations he had cheated first began to surface, Han had denied any wrongdoing - but said he had changed his mind after thinking about the feelings of the candidate who had come second in the exam.
He went on to apologise to the other entrants who had passed the tests fairly.
