South Korea Tax Exam Top Scorer Admits to Using Generative AI to Cheat

The top scorer in South Korea's national tax accountant qualification examination has admitted to using generative artificial intelligence and micro-cameras to cheat during the tests. The confession follows months of public speculation surrounding his near-perfect results and has prompted government action ahead of the country's upcoming national college entrance examination.

The candidate, identified by his surname Han, acknowledged his actions in a video published on the YouTube channel Attorney Lee Don-ho while wearing a face mask. Han admitted that he passed the exam using electronic devices and generative AI, stating that his top score was not the result of fair effort. He publicly apologized and confirmed that his lawyer had submitted a written confession to the Seoul Metropolitan Police Agency. Police confirmed receipt of the confession on Sunday morning and stated that investigators have been assigned to the case.

METHOD OF CHEATING AND SUSPICIONS

Han secured the top ranking in both the April and July rounds of the qualification exam. During the first round, he achieved a score of 397.5 out of 400 points, answering 159 out of 160 questions correctly. The remarkably high score led to allegations that he used smart glasses to cheat, an accusation he initially denied.

According to his confession, Han used a micro-camera to capture images of the exam questions. He then transmitted the photos to an AI tool and reviewed the generated answers on a smartphone while taking the tests.

GOVERNMENT RESPONSE AND UPCOMING COLLEGE ENTRANCE EXAM

The scandal has created significant concern across South Korea, where performance on standardized tests heavily influences career prospects and social mobility. The revelations come directly before Thursday's annual national college entrance exam, a pivotal event for students across the nation.

In response to the incident, a senior presidential office official stated on Sunday that the presidential office views the situation very seriously and is preparing countermeasures. The official added that concerns regarding potential cheating on national qualification exams prompted the presidential chief of staff for policy to convene an emergency meeting. Prime Minister Han Seong-sook also acknowledged public anxiety regarding AI-assisted cheating, promising that the government will oversee the upcoming college entrance exam closely to maintain fairness.
