Top scorer in South Korea tax exam admits using AI to cheat

A candidate in South Korea who achieved a near-perfect score on a rigorous tax accountant exam has confessed to using generative AI to cheat. The individual, identified as Han, admitted to using a microcamera and smartphone to feed questions to an AI tool. This scandal has triggered major concerns ahead of the country's high-stakes national college entrance exam.

According to reports, the candidate identified as Han ranked first in both rounds of South Korea's tax accountant qualification exams held in April and July. In the first round, he scored 397.5 out of 400 points, getting only one question wrong out of 160. Initially, he denied accusations of cheating with smart glasses, but he later confessed through his lawyer on a YouTube channel, stating that he used a microcamera to photograph exam questions, sent them to an AI tool, and checked answers on a smartphone. He has since submitted a written confession to the Seoul metropolitan police agency.

The incident has severely rattled South Korea, where standardized testing heavily dictates social mobility. With the annual national college entrance exam approaching, the presidential office and prime minister's office have stepped in, holding emergency meetings and vowing to implement strict countermeasures to ensure test fairness.
