About the “1000 Key Questions” for 2026

1.
Correction, supplementation, and systematization of fingerprints and commentary

In the 2026 edition, some "passages" and "commentaries" have been revised and supplemented with more accurate and clear sentences. Furthermore, passages on the same topic, previously scattered across multiple questions, have been consolidated into a single question, facilitating more systematic learning.

2.
Added the latest past exam questions

The 2026 edition reflects the content of previous exam questions administered by the Bar Examination, Police, Prosecutors' Office, and Courts up to July 2025 (24-year police officer 2nd round, career recruitment, 7th grade prosecutor, Coast Guard officer, police academy transfer, lawyer, Coast Guard promotion, police promotion, 25-year police officer 1st round, 9th grade prosecutor, 9th grade court, Coast Guard police officer? Department, Criminal Law Ability Evaluation, Police Superintendent open recruitment).
I think that the accuracy rate has also been greatly improved by making the gaps more densely filled.

3.
Add the latest case law

By adding the latest case law that has not yet been tested but is highly likely to be tested (reflecting case law up to July 2025), we have been able to completely supplement any loopholes or blind spots that may arise when studying only with past exam questions.
Among the latest case laws over the past five years, the cases with a particularly high possibility of being tested are marked as [25 Latest Case Laws] so that they can be used in the final organization.
The latest case law added to the 2025 edition was confirmed to have been mostly accurate in the exams administered in the latter half of 2024 and 2025.

In any exam where the competition rate exceeds 10:1, a learning attitude that strives for perfection rather than moderate study is necessary.

I hope that you will make good use of this book and achieve victory by wearing the laurel wreath.
