Regarding the allegation of a leak of the Yonsei University's regular admission essay test questions that occurred in October last year, police concluded that the questions were not leaked online before the exam started. However, one candidate took photos of the test questions before the exam began and solved them using ChatGPT, which were then submitted to the prosecution. This candidate failed because ChatGPT provided incorrect solutions.
On the 9th, the Seoul Metropolitan Police Agency's Public Crime Investigation Unit announced that only one of the eight authors of a post that uploaded the Yonsei University regular admission essay questions to the online community DC Inside was sent to the prosecution without detention on charges of obstruction of duty.
The seven individuals who were cleared of charges took photos of the test paper and other materials with their mobile phones and posted them on the DC Inside bulletin board after the essay test time had ended. Since they posted it after the exam time ended, charges of obstruction of duty were not applied. The individual sent to the prosecution committed fraudulent behavior by taking a photo of the test paper that had been distributed in advance due to an oversight by the supervisor and solving the questions using ChatGPT.
Earlier, at a test center for the Yonsei University natural science regular admission essay test held in October last year, the supervisor mistakenly distributed the test paper about one hour before the exam started. Yonsei University explained that the supervisor distributed the test paper at 1 p.m. and realized the mistake, recovering it at 1:07 p.m. However, candidates claiming to have been harmed by this incident stated that the test paper was exposed to candidates for up to 20 minutes between 12:55 p.m. and 1:15 p.m.
As a result of this incident, candidates and the school engaged in legal disputes. Yonsei University eventually conducted a second test for all candidates of the natural science essay test on December 8 last year. They also selected 261 candidates in the second test, along with the 261 candidates chosen from the first test, to ensure no student was disadvantaged. This year, 10,444 candidates applied for the Yonsei University natural science essay test, and 9,666 took the exam.
