One question from the math section of the College Scholastic Ability Test 2018, also known as Suneung, had the high school seniors scratching their heads in confusion, which was deemed by many as the most difficult question from the test.
"EXO sent me to college," said the high schooler.
One student, however, got the toughest question right by making an "educated guess."
"EXO sent me to college," tweeted the elated senior. "I was having trouble understanding the question, and at the last minute, I guessed 9 as the answer only because there are nine members in EXO," she explained her methodology.
She thanked the group, of which she has been a fan for a long time. "You should all be fans of EXO - it pays off," she added.
