1.
The best vocabulary for the civil service exam
With just one volume of 『2026 Simpson Vocabulary』, you can thoroughly prepare for civil service vocabulary.
This book contains 2,500 frequently appearing keywords, carefully selected from the 2025 National Civil Service Exam Level 9, sample questions from the Ministry of Personnel Management's 1st and 2nd exams, 10 years of previous civil service exam questions, and the know-how of Professor Woo-cheol Shim, who has taught the College Scholastic Ability Test (CSAT) and civil service exam preparation for 30 years.

2.
Includes 'Practical Vocabulary' for Civil Service Exam Preparation
As the national civil service exam, Grade 9, will shift its focus to practical work from 2025, we have selected 200 practical vocabulary words.
Organizing vocabulary related to work or jobs by topic helps you prepare for everyday English and new types of reading passages.


3.
Situational English Expressions for Daily Life
Among the expressions that appeared in the civil service exam's daily English passages or options, expressions that require memorization or reference have been classified by situation and included.
It is a good idea to learn these expressions in advance so that you can quickly grasp the flow of the conversation when solving problems.

4.
'Headword + Derivative/Synonym/Example' structure for highly efficient vocabulary learning.
To reduce the burden of learning, 『2026 Simpson Vocabulary』 has selected only important core vocabulary as headwords, but has expanded the vocabulary with derivatives, synonyms, example sentences, and appendices (basic vocabulary) to enable extensive learning.
In particular, with the latest revision in 2026, we have put a lot of effort into revising the derivatives and synonyms section, deleting as many minor words as possible and adding new words that have recently become important.

5.
Vocabulary learning using diagrammatic 'etymology and association'
Etymology and association play a significant role in learning English vocabulary.
Accordingly, 'Etymology-centered vocabulary' divides and diagrams each vocabulary based on roots, prefixes, and suffixes, and 'Association-centered vocabulary' adds an associative explanation using the pronunciation and form of each vocabulary.
Learners can increase their interest in learning and achieve powerful memorization effects through these two learning methods.

6.
Learning 'synonyms' through repeated exposure
To help test takers memorize synonyms, which is the most difficult part, the vocabulary in the title appears multiple times as synonyms for other titles.
Repeated exposure to vocabulary can ultimately lead to long-term memory effects.

7.
Providing free learning materials to maximize learning effectiveness
We provide a variety of learning materials, including audio MP3 files that allow you to memorize vocabulary by listening to them regardless of time and place, video lectures by teacher Shim Woo-cheol, subjective test papers, and services through the Memorization Whale Vocabulary APP.
