Seoul: South Korea’s top scorer in this year’s national tax accountant examination has admitted to using artificial intelligence (AI) and electronic devices to cheat, ending months of speculation over his unusually high marks. The confession has sparked fresh concerns about examination security.
The candidate, identified by his surname Han, made the admission on Sunday, November 15, through a video published on his lawyer’s YouTube channel. He acknowledged using a microcamera, a smartphone and generative AI to obtain answers during the examinations.
Han explained that he photographed examination questions using a miniature camera, transmitted the images to an AI tool and checked the generated answers on his smartphone. He also apologized for undermining the fairness of the qualification process.
The candidate said he had submitted a written confession to Seoul police detailing his actions. He indicated that some electronic devices had been damaged, but he intended to provide the remaining materials and evidence to investigators.
The controversy surrounding the south korean tax exam began after Han achieved exceptionally high marks in both examination stages held in April and July. His results raised questions among other candidates and attracted widespread attention online.
In the first stage, Han scored 397.5 out of 400, answering 159 of the 160 questions correctly. He subsequently secured 663 out of 800 in the second-stage written examination, finishing as the overall top scorer.
His performance was particularly striking because the first examination included several subjects with challenging questions. The near-perfect result led to speculation about whether advanced electronic equipment or artificial intelligence had been involved.
Han initially rejected allegations of cheating and defended his examination performance. However, he later acknowledged that his previous explanations were untrue and accepted responsibility for both the misconduct and his attempts to conceal it.
In his public apology, Han said his achievement was not the result of legitimate effort. He also expressed regret toward other successful candidates, examination participants and professionals working in the tax accounting industry.
The candidate reportedly cited financial difficulties, business problems and pressure surrounding his career as reasons behind his decision. He said anxiety about the length of the examination preparation process also influenced his actions.
The admission has raised wider questions about how examination authorities can prevent candidates from using hidden electronic devices and AI-powered tools during high-stakes professional qualification tests.
The controversy comes just days before South Korea’s annual national college entrance examination, scheduled for Thursday, November 19. The examination, widely known as the Suneung, is one of the country’s most important academic events.
South Korea’s university entrance examination attracts significant national attention because students’ results can influence their university admissions and future career opportunities. The latest cheating scandal has increased pressure on authorities to strengthen examination security.
Prime Minister Han Seok-sook said the government would prepare thoroughly and closely supervise the college entrance examination to ensure it takes place fairly and without disruption.
The government is expected to pay particular attention to examination procedures and potential misuse of artificial intelligence as concerns grow about technology-assisted cheating.
The incident also highlights a growing challenge for education and professional certification authorities worldwide. Generative AI tools can process photographs of questions and provide answers quickly, creating new difficulties for traditional examination security systems.
South Korean authorities now face questions about the validity of the candidate’s results and the effectiveness of existing monitoring procedures. The police are expected to examine the submitted confession and available evidence as part of their investigation.
