2026 Easy Administrative Law
Yoo Hwi-woon Administrative Law

"2026 Yoo Hwi-un Administrative Law General Theory Summary Notes + Past Exam Questions (Yo.P.)" is a single-volume textbook that integrates core theories and past exam questions into a 2-in-1 format, allowing students to learn civil service administrative law theory and exam trends in a short period of time. The features of this book are as follows.

① A 2-in-1 summary book that combines 『Summary Notes』 and 『Previous Exam Questions (OX and 4-option Multiple Choice)』 in a 1:1 ratio.

This textbook is a combination of 『Summary Notes』 and 『Previous Exam Questions (False or Four-Option Multiple Choice)』, and is structured to allow for efficient simultaneous study of theory and previous exam questions by matching them 1:1.
The actual past exam questions that served as the background for the summary on the left were placed immediately to the right, and a diagram that organized the past exam questions on the right into an organized structure was placed immediately to the left, and then the two were matched by number.
The included past exam questions consist of approximately 4,730 questions from 19 years of exams, with duplicates removed, providing a sufficient range to ensure passing.

② A separate keyword commentary book, “Yoki,” is provided for each fingerprint.

We provide a separate volume (Yoki) of all 4,730 texts in this book, block-by-block, using highlighters to indicate where keywords are and where to pause reading.
Additionally, by presenting incorrect passages on the left and correct passages on the right, it is possible to intuitively identify the issue and quickly derive the answer, minimizing the amount of study while increasing the accuracy of learning.
After reaching a certain level, complete self-study and efficient learning is possible with just Yoki.


③ All 4,730 fingerprints are assigned a 9-level importance rating (S, A, B, C, Gi, In, So, Mu, Ji). Both true and four-option multiple-choice questions are included.

All 4,730 fingerprints are marked with a 9-level importance level (S, A, B, C, Gi, In, So, Mu) and minor fingerprints are marked separately, allowing users to adjust the intensity of their own learning.
In addition, there are many 4-option multiple choice questions in addition to true or false questions, so you can study thoroughly from the basics to the most difficult level.

④ Provision of notes and acronyms

To facilitate intuitive understanding, schematic notes are abundantly placed in the margins of the textbook, and acronyms are also placed in the margins of relevant sections to facilitate quick and effective memorization.

⑤ Perfectly reflects the latest questions from 25 years, latest case law, and revised laws.
We also provide sample questions from previous exams.

This textbook reflects the latest case law and the most recent exam questions from 2025, enabling learning in line with exam trends. It also includes the latest legal information, adding and revising it to ensure up-to-date learning without any additional effort.
In addition, parts that were not included in the exam but are expected to appear in the exam were included as problems (200 passages, approximately 50 questions).

⑥ Effective learning using the 『Administrative Law by Yoo Hwi-un』 APP
