I don't have a killer question. Why is it so hard?Attractive incorrect answers.

The Ministry of Education said it will continue to exclude killer questions from the CSAT this year.

I thought the test would be a little easier without killer questions, but the mock evaluation in June turned out to be quite difficult.

Reporter Yeom Hye-won reports on why and how the test takers should prepare.

The mock evaluation in June was the so-called "insertability test."

Just by looking at the standard score peak that gets higher as it gets harder,

Korean language was similar to last year's CSAT, which had a high level of difficulty, and the math was rather higher.

English was also not easy enough to have a first-class ratio of around 1%.

Civic groups criticized some of the questions with low correct answer rates as questions outside the curriculum.

It's a real killer question.

However, the government dismissed it as a difficult level to handle within the curriculum.

Nevertheless, he explained that the students were wrong a lot because they presented a tricky view.

It means that a lot of so-called 'attractive incorrect answers' were inserted.

Experts predicted that this trend will continue in the CSAT.

In particular, it is predicted that this type of discrimination will be secured not only in the top but also in the middle level.

[Kim Byung-jin / Director of E2US Educational Evaluation Institute: If it takes a long time in the beginning, the problems in the latter part, that is, questions of difficulty, come out more easily than usual, but it often results in not being able to approach the problem.]

It is essential to secure discrimination power as the number of N-submersible has been driven to the highest number of N-submersible in history.

In the end, the prediction that the trend of non-CSAT without killer questions will continue this time is gaining strength.
