Mostly True
A notice posted by a professor at Konkuk University calls for an in-person retest covering roughly 600 students, according to the original announcement reviewed for this report. The notice was distributed through a course page restricted to enrolled students, and no publicly accessible URL of the announcement is available.
The announcement, issued by a Konkuk University professor, states that an in-person retest would be administered to about 600 students. The notice was posted on a class management page that requires authentication, meaning the full text is not publicly viewable.
Because the original notice sits behind an authenticated course page, independent access to the full document was not possible. The assessment therefore rests on the notice as reviewed, and no additional figures beyond the approximately 600 students appear in the available material.
The announcement is not a captcha-protected page but an authenticated class notice, which limits outside verification of its contents. Konkuk University's official website materials were consulted alongside the notice, but the university itself has not issued a separate public statement on the retest.
It remains unconfirmed whether the retest applies to a single course or spans multiple sections, and no details on the timing or format of the retest are available in the reviewed material.
The claim that a 600-person in-person retest was announced by a Konkuk University professor is supported by the original notice, though restricted access to the authenticated class page leaves some details unverified — making the claim Mostly True.
