The announcement of scores for the 2024 College Scholastic Ability Test(CSAT) held last month included one perfect score in all subjects.

The education ministry and state test administrator held a briefing on the results on Thursday, assessing the test to be more difficult than last year’s despite the exclusion of the so-called “killer questions” on materials not included in the standard public school curriculum.

The highest standard scores in the Korean language and math sections both increased compared to last year.

The standard score is calculated by comparing the average for the subject against the highest, with a lower average increasing the top student’s standard score.

If the highest score is close to 150 points, the test is evaluated as “difficult.”

In the Korean language section, the highest standard score was 150, 16 points higher than last year’s CSAT, while the highest standard score in the math section was three points higher at 148.
