Every November, South Korea comes to a standstill for its infamous college entrance exam.
Shops are shut, flights are delayed to reduce noise, and even the rhythm of the morning commute slows down for the students.
By late afternoon, most test-takers walk out of school gates, exhaling with relief and embracing the family members waiting outside.
But not everyone finishes at that hour. Even once darkness has fully settled and night has set in, some students are still in the exam room - finishing close to 10pm.
They are the blind students, who often spend more than 12 hours taking the longest version of the Suneung.
