South Koreans sit key exam as flights halted to limit distraction

SEOUL - More than half a million students in South Korea are sitting the crucial national university entrance exam, with authorities set to take extraordinary measures including halting flights to minimise distraction.

The nine-hour test, which is being taken by 504,588 pupils this year, is crucial for securing spots in top universities. It is also considered key to elevated social status, lucrative careers, and even marriage prospects.

Enormous pressure placed on students in South Korea's ultra-competitive education system has been blamed for teenage depression and suicide rates which are among the highest in the world.

The importance of the test was reflected by the aggressive measures authorities were taking to prevent any disturbance.

To reduce noise disruption during the listening portion of the English test, Seoul's transportation ministry has announced a nationwide ban on all aircraft takeoffs and landings outside of emergency situations.

With the exception of aircraft in distress, all airborne planes must maintain an altitude higher than 3,000m during the restricted time.

More than 90 flights had to be rescheduled because of the exam.

Public offices and major businesses were requested to adjust their opening hours to 10 am or later to alleviate traffic congestion and ensure that students arrived on time for the nationwide exam.

The stock market also opened an hour later than usual. 

Police cars and regional government officials were on standby to help students running late for the exam reach their test sites in time.

This year's test also marks the first time that test-takers are allowed to take the exam without wearing masks since the pandemic began.
