Hotel Shilla President Lee Boo-jin's eldest son, Im Dong-hyun, took the stage as a speaker at a grade management session for his high school juniors. Im was said to have shared methods for managing school grades and subject-by-subject strategies for the College Scholastic Ability Test, based on materials he organized and his study experience.
According to Maeil Business Newspaper, Im joined the "Pre-freshman year, Whimoon High grade briefing" at a private admissions academy in Daechi-dong, Seoul, on the 2nd in the afternoon and explained study habits and test-prep tips that juniors could use as references.
The title of the materials Im prepared was said to be "A Whimoon life with no regrets." The materials reportedly included the learning flow over the three years of high school, tips for school grades and the CSAT, and advice he wanted to offer to his juniors.
The subject-by-subject tips were specific. For Korean, he emphasized the ability to understand passages accurately and repeated practice with past questions, while including advice to be wary that the logic of poor questions from privately made mock tests can stick as a habit. For math, he reportedly said students should prepare for problems that require thinking skills, backed by a sufficient volume of problem solving, and recommended organizing one's own solution methods and practicing them repeatedly.
Im also was said to have given his juniors the message that "school grades and the CSAT are not an either-or choice, but something you must carry together to the end," along with advice that there is a need to strictly curb smartphone and game use during the three years of high school to maintain focus.
Meanwhile, Im was admitted to the economics department at Seoul National University for the 2026 academic year. While attending Whimoon Middle School and Whimoon High School in Seoul, he reportedly stayed at the very top of the liberal arts track and excelled in math.
