Suneung Day: When a Whole Country Comes to a Standstill — A Record of Korea's College Entrance Exam Day

One Thursday morning in November, Seoul’s subway trains come more often than usual. Office workers head in late, and the stock market opens an hour behind schedule. Just after 1 PM, not a single plane leaves the runway at Incheon Airport. Somewhere, artillery drills go silent, and construction sites pause their loudest work.

No war has broken out, and there is no national ceremony underway. It is the day high school students sit an exam.

What exactly is the Suneung?

Its formal name is the Daehak Suhak Neungnyeok Siheom — the College Scholastic Ability Test — but everyone simply calls it the Suneung. English speakers usually say CSAT. Almost every Korean university weighs this score in some form, and the exam is held just once a year, over a single day. There are no retakes.

What does the day’s schedule look like?

Students must be seated by 8:10 AM, and anyone sitting every section finishes at 5:45 PM. It is exactly a nine-hour-and-five-minute day.

A few things stand out. Lunch is eaten at your own desk. The test site provides neither food nor drinking water, so everyone brings their own lunch box. There are no wall clocks in the exam room, so you must bring your own watch, too. And the English section begins not with a bell but with a broadcast signal: at 1:07 PM a three-minute sound check plays, then rolls straight into the listening test.

Why don't planes fly that day?

Because of the English listening test. For a listening section that wraps up within 25 minutes, the Ministry of Land, Infrastructure and Transport grounds all takeoffs and landings at every airport for 35 minutes, including five minutes on either side.

On November 13, 2025 — the 2026 school year exam day — the window ran from 1:05 PM to 1:40 PM. A total of 140 flights, 65 international and 75 domestic, had their schedules adjusted. Planes already in the air circled and held above 3 km. Only emergency aircraft were exempt.

How does Korea’s schedule change that day?

To keep students from being late through traffic, the whole country pushes back its start times. Here is what was actually put in place on November 13, 2025.

🚦 Measures actually in force on the 2026 school year exam day (Nov 13, 2025)

Seoul’s districts deployed 646 student transport vehicles to major intersections and stops, ferrying worried latecomers free of charge. Police patrol cars did the same. On November 13, 2025, the Gyeonggi Nambu police received 153 Suneung-related emergency calls between 7:00 and 8:30 AM — 88 requests for student transport, 8 lost or missing exam tickets, and 4 cases of students heading to the wrong test site. Busan logged 66 calls the same morning. There was even a case where a highway accident blocked the road and a patrol car carried a student all the way to their Seoul test site.

What happens outside the test site?

From about 7 AM, a crowd gathers at the front gate. Most of them are younger students — sophomores and freshmen from the same school, wearing sashes with cheering slogans over their uniforms, beating drums and chanting. They call out the names of arriving seniors, grab their hands, and press hand warmers into them. A Seoul morning in mid-November is usually cold.

The parents are elsewhere. After watching their child walk through the gate, many head to a temple, cathedral, or church. The main hall of Jogyesa Temple in Seoul is so packed the day before the exam that there is nowhere to sit. Every year the papers run stories of grandparents who came to pray without missing a single day for over 100 days. Gatbawi, a rock-hewn Buddha on Palgongsan in Daegu, is famous for the belief that it grants one wish — but to make that wish, you have to climb 1,365 steep stone steps.

How important is the Suneung for admission, really?

Here is the surprise. For an exam that makes a whole country clear its schedule, the share of seats decided purely by the Suneung score is smaller than you would think.

📋 Composition of 2027 school year admission quotas (all universities nationwide)

The 2027 school year is the first time early admission has crossed 80%. Most early-admission spots are based on student records — grades and activity logs from all three years of high school. So arithmetically, only about 18% of all seats come down to the Suneung score.

Yet the exam still carries this much weight for two reasons. First, most early-admission tracks impose a minimum Suneung score requirement — even if your grades and documents get you to the borderline, miss the required grade on the Suneung and you are out. Second, top Seoul universities and medical schools reserve a much larger share for regular admission than the national average. The more competitive the seat, the bigger the Suneung’s stake.

Did the exam get easier after they scrapped the "killer questions"?

It did not. In 2023, the government announced it would stop writing killer questions — ultra-hard items outside the public school curriculum that could only be cracked with private tutoring — and that policy has held for three straight years. Yet the difficulty debate returns every year in a new shape.

The 2026 school year scoring results show why.

📈 Difficulty indicators for the last two exams (KICE scoring results)

A higher top standard score means a harder exam. Korean jumped 8 points in a single year, and the number of perfect scores fell to a quarter of the previous year. After criticism that the prior exam had too many perfect scores to rank students, the difficulty was tightened back up. Remove the specific category called “killer questions,” and the underlying job — ranking half a million people in one day — has not changed, so the calibration problem will keep recurring.

The private-tutoring figures point in a slightly different direction. Total private education spending for K-12 students in 2025 was ₩27.5 trillion, down ₩1.7 trillion from the year before — the first decline in five years. The participation rate also dropped 4.3 percentage points to 75.7%. But among students who do get tutoring, average monthly spending per person actually rose 2.0% to ₩604,000. Fewer families take part, but the ones who do spend more.

What does a traveler experience in Seoul that day?

It will not wreck your itinerary. But you will clearly feel the day running on a different rhythm.

🗺️ Seoul on exam day: what changes hour by hour

The evening after the exam is nothing like that morning. Flash your exam ticket and you get discounts at theme parks, cinemas, hair salons, even on flights. Some years the deals — up to 25% off domestic round trips and 10% off international — run through the end of December. The eighteen-year-olds who were hauling cram-school backpacks the day before now fill the streets of Hongdae and Gangnam.

Pass through Daechi-dong or Mok-dong, Seoul’s hagwon (cram school) districts, during the day and you will see them eerily empty. The good-luck banners still hang on every academy building, but the students who should be inside are all at the test site. It is a sight that exists for exactly one day a year.

When is the next Suneung?

The 2027 school year Suneung falls on Thursday, November 19, 2026, with results released on Friday, December 11. The sections — Korean, math, English, Korean History, electives, and second foreign language and Classical Chinese — are unchanged, as is the common-subject-plus-optional-subject structure for Korean and math. Only Korean History is compulsory; everything else is optional.

But this exam is expected to be the last of the current system. With the admissions overhaul taking effect from the 2028 school year, the 2027 school year will be the final Suneung in the optional-subject format.

If you are in Seoul that day, I would suggest glancing outside in the morning. The city starts a little later and a little quieter than usual. And at 1:05 PM, look up. For 35 minutes, nothing crosses the sky.
