South Korea’s top tax examination scorer has admitted using generative AI and electronic devices to cheat in national tests.

How Did the Candidate Use AI to Cheat?

A candidate identified by the surname Han admitted on Sunday, November 15, that he had used a microcamera, smartphone and generative artificial intelligence to obtain answers during South Korea’s national examination for aspiring tax accountants.

Han said he photographed examination questions using a concealed microcamera, submitted the images to an AI tool and checked the generated answers on his smartphone. His admission followed months of speculation after he achieved near-perfect marks across hundreds of questions in examinations conducted in April and July.

What Did the Top Scorer Confess?

In a video published on the YouTube channel of attorney Lee Don-ho, Han acknowledged that his examination results had been obtained dishonestly and apologised for his actions.

“I cheated using electronic devices and generative AI. My passing the exam with the top score was not the result of fair effort,” he said. Appearing on camera wearing a face mask, Han also stated that he had submitted a written confession to Seoul police.

How Has the Government Responded?

The admission has raised concerns among South Korean authorities ahead of the country’s annual national college entrance examination, scheduled for Thursday. A senior presidential office official said the government regarded the matter seriously and was preparing measures to prevent similar misconduct.

The official said the presidential chief of staff for policy would convene an emergency meeting to address reports of possible examination cheating. Prime Minister Han Seok-sook had also acknowledged public concerns about AI-assisted cheating on Friday and pledged preparations to ensure the college entrance examination was conducted fairly.

Why Has the Case Raised Wider Concerns?

The incident has attracted attention in South Korea, where standardised examinations play an important role in determining educational opportunities and career prospects. The confession has brought renewed scrutiny to the potential misuse of generative AI during high-stakes assessments.

Authorities are facing questions about examination safeguards as increasingly accessible AI tools create additional opportunities for misconduct. Han’s account illustrates how concealed recording equipment and AI-generated responses can be combined to circumvent examination rules.

The case also highlights the importance of effective monitoring and preventive measures in maintaining confidence in competitive examinations. South Korean officials have emphasised their commitment to ensuring fairness as the national college entrance examination approaches.
