As the September mock evaluation for the 2027 College Scholastic Ability Test (CSAT) was administered on the 2nd, the results of a survey on test-takers' perceived difficulty are drawing attention. According to a perceived difficulty survey conducted on the EBSi website, a total of 108 respondents had answered as of 2:25 p.m. that day. Of the respondents, 63.9% rated the test as 'very difficult,' while 13.0% said it was 'somewhat difficult.' Combined, the proportion of those who felt the test was difficult reached 76.9%. In contrast, only 11.1% said it was 'average.' 'Very easy' accounted for 8.3% and 'somewhat easy' for 3.7%, meaning responses indicating the test was easy totaled 12.0%. However, it should be noted that these results were tallied shortly after the survey began. Given that only 108 people participated, the perceived difficulty ratios may change as the number of respondents increases. Meanwhile, this September mock evaluation for the 2027 school year was administered by the Korea Institute for Curriculum and Evaluation. It draws attention as a test that allows students to assess their academic level and gauge the question trends of the upcoming CSAT.
