“Weren’t You Wearing AI Glasses?” ... The Decision by an SNU Student, the “Perfect LEET Scorer” Under Suspicion

[Financial News] Allegations that the top scorer on the tax accountant exam cheated using AI smart glasses have now spread to the first person ever to achieve a perfect score on the Law School Admission Test (LEET). After seeing reactions questioning their score, the LEET perfect scorer said they would prove their ability by solving the Korean section of the College Scholastic Ability Test (CSAT) live.
According to education sources and others on the 13th, A, the LEET perfect scorer currently enrolled in Seoul National University’s Department of Dentistry, left a pinned comment on the previous day’s video featuring them on the Mimiminu YouTube channel and said on social media (SNS), “I’ll solve the Korean section of the 2027 CSAT live.”
A plans to prepare for a live broadcast starting at 8:40 a.m. on the 19th, the day the CSAT is administered, and print the Korean section question paper as soon as it is posted on the Korea Institute for Curriculum and Evaluation website at 10:56 a.m.
A plans to solve the questions from 11 a.m. to 12:20 p.m., for the same 80 minutes allotted to the actual CSAT Korean section. The process will be livestreamed in an unedited “one-take” format, filmed in a single continuous shot.
Details such as the proctors, the location and the broadcast channel are to be decided and announced by the 16th.
A’s announcement of a public test of their abilities comes amid recent allegations of cheating surrounding the top scorer on the tax accountant exam.
B, who placed first in the 63rd first-stage tax accountant exam held in April, answered 159 of the 160 questions correctly, scoring 397.5 out of a possible 400 points.
B also received perfect scores in Introduction to Tax Law, where the average score was 30.18, as well as Introduction to Accounting and Commercial Law. In particular, no examinees were reportedly found to have scored 90 or higher in Introduction to Tax Law.
After these results became known, some examinees and practicing tax accountants questioned them, calling the score “impossible within the time limit.” In particular, some alleged that B may have cheated using smart glasses equipped with AI features.
In a media interview, B denied the allegations, saying, “If you can get a perfect score with AI glasses, there’s no reason to study.”
The Human Resources Development Service of Korea, which administers the exam, also said, “A review by four proctors found nothing unusual,” but some examinees continue to raise suspicions.
The Human Resources Development Service of Korea has commissioned experts to conduct a detailed review of B’s answer sheet for the second-stage tax accountant exam.
The controversy surrounding the tax accountant exam also affected A, who achieved the first perfect score across all sections of the 2027 LEET, held in July.
A answered every question in Language Comprehension and Logical Reasoning, becoming the first person to achieve a perfect score across all sections in the 19 years since the LEET was introduced. However, some internet users also raised the possibility that A had cheated using a smart device.
A reportedly received a grade of 7 in the Korean section of a previous CSAT, but earned a perfect score on the 2026 CSAT. A had said they took the LEET to test their study methods; this time, they say they will prove their ability by solving the questions live.
As concerns grow over cheating on exams using wearable electronic devices such as AI smart glasses, exam administration bodies are also preparing related measures.
The Ministry of Education has designated AI smart glasses as prohibited items at test sites, starting with the 2027 CSAT being administered this year. The Human Resources Development Service of Korea also plans to introduce a system of dedicated proctors to check whether smart devices are being used.
