"Sunny Administrative Law General Theory Core Intensive" is a textbook cited by those who passed the national, local, fire, and military civil service exams as the secret to high scores. It is the most strategic and efficient summary book that organically links "core theories" and "previous questions."

In particular, 『2026 Sunny Administrative Law General Theory Core Intensive』 combines the previously separate 'Theory' and 'Problem' sections into one volume for ease of publication.
This revised edition allows you to organically examine 'theory' and 'problems' at a glance, and the theory has been organized more compactly.
In addition, the questions include not only past exam questions but also questions that have not been tested before, ensuring that you will not be lacking in exam preparation.
In addition, although it is not a frequently asked topic, we have strengthened the content by including the contents of the “Personal Information Protection Act”, which was provided as special lecture material in case of an emergency, as an appendix along with true or false answers from previous exam questions.
We also focused on improving readability by increasing the format and increasing the font size used in tables, case law, and articles.

The specific features and structure of this book, which adds new things every year, are as follows.

01 The theory is on the left page, and the true or false questions from previous exam papers, explanations, and answers are on the right page, so the theory and questions are included in one book.
'Theory-true/false/explanation (correct passage)' are all matched 1:1, and after learning the theory, you can solve true/false questions from the past passages and check the explanation for the 'correct passage', thereby increasing learning efficiency by allowing you to have the effect of reading three times with just one study.

02 Essential topics were selected and organized into 75 TOPICS, and the core theories were condensed using tables, diagrams, and concise text.

03 The revised laws, such as the Basic Administrative Law, the State Compensation Act, and the Personal Information Protection Act, are marked with a 'Revised' or 'New' icon, and the latest case law from 2022 to 2025 is marked with a 'Latest' icon.
In addition, we have marked the 'Unpublished' icon for sections that have not yet been tested but are likely to be tested in the future, and we also provide various study tips, such as 'Sunny Teacher TALK'.

04 The true or false questions in the past exam papers include the 9th, 7th, and 5th grade military service exams, 7th grade national civil service exams, and 7th grade local civil service exams in Seoul in 2024, as well as the 9th grade police officers, coast guard officers, firefighters, lawyers, 9th grade firefighters, 9th grade national civil service exams, 8th grade administrative officers, and the latest past exam papers up to the 9th grade local civil service exams and Seoul Metropolitan Government exams implemented on June 21, 2025, to ensure that you can obtain the learning effect of reading past exam papers.
In particular, since we have covered theories, articles, and precedents from previous exams, you will be able to fully prepare for new passages.
In addition, the importance of the problem was indicated in 5 levels to adjust the intensity of learning.

05 For each true or false question in the previous exam paper, a detailed and helpful explanation is provided to the right of the correct answer so that you can use it to study the correct answer.
Additionally, the key parts of the explanation are highlighted in color so that you can quickly organize the content by only looking at the key parts, so please use them repeatedly until right before the exam.

06 The appendix includes important contents of the Personal Information Protection Act and additionally includes a key plus table summarizing various comparisons.
In addition, we have included a coupon for the 『2026 Sunny Administrative Law APP』, which allows you to easily learn administrative law anytime, anywhere.
We hope you will study effectively by using both the 『2026 Sunny Administrative Law General Theory Core Focus』 and the 『2026 Sunny Administrative Law APP』.
