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.
On Thursday, more than 550,000 students across the country will sit for the Suneung – an abbreviation for College Scholastic Ability Test (CSAT) in Korean. It is the highest number of applicants in seven years.
The test not only dictates whether people will be able to go to university, but can affect their job prospects, income, where they will live and even future relationships.
Depending on their subject choices, students answer roughly 200 questions across Korean, mathematics, English, social or natural sciences, an additional foreign language, and Hanja (classical Chinese characters used in Korean).
For most students, it is an eight-hour marathon of back-to-back exams. They begin the Suneung test at 08:40 and finish around 17:40.
Blind students with severe visual impairments, however, are given 1.7 times the standard testing duration.
This means that if they take the additional foreign language section, the exam can finish as late as 21:48 – nearly 13 hours after it began.
There is no dinner break; the exam continues straight through.
The physical bulk of the braille test papers also contributes to the length.
When every sentence, symbol and diagram is converted into braille, each test booklet becomes six to nine times thicker than the standard equivalent.
