INDEX

Take the civil service exam with just one vocabulary textbook!!

1.
High-frequency words/key phrases/idioms in one book!
We thoroughly analyzed all past exam passages up to the 2025 National Civil Service Exam, the latest exam, to reflect all key words.
In addition, this book condenses all of the frequently appearing "words" as well as the core "idioms" and frequently appearing "idioms" that appear in the civil service exam into one volume.
Therefore, you can take the civil service exam with just this one book, 『Jo Tae-jeong's English Civil Servant Vocabulary Route』, without the inconvenience of purchasing multiple separate vocabulary and idiom textbooks.

2.
Most frequent synonym/antonym concepts that enhance vocabulary inference skills
Includes all necessary synonyms/antonyms.
We have carefully selected and included the essential synonyms and antonyms so that you can correctly acquire the concept of synonyms and antonyms, which can be considered the basis of vocabulary logical reasoning.

3.
A summary of similar concepts to reduce memorization time
We've organized similar concept words so you can see them at a glance.
For example, when memorizing “reptile,” “amphibians,” “mammal,” “rodents,” and “primates” are included at the same time so that you don’t have to look up similar words separately.

4.
A compilation of the most frequent roots to enhance your vocabulary
For the most frequent roots, we have organized them so that you can learn derived vocabulary together.
In the case of “identification” (ID, sameness) that appeared in the 2025 Civil Service Exam English Question 1, it is the most frequently appearing word, so its related derivatives, identify (confirm) and identity (sameness), were included together to help you see it all at once and maintain a sense of the word for a long time.

5.
Organizing confusing words to enable reliable memorization
We have included words that are confusing due to their similar appearance/similar pronunciation so that you can immediately check and compare them.
Words that are similar in appearance or pronunciation, such as “adapt”/“adopt”/“adept”, “preserve”/“persevere”, etc., are included repeatedly each time they appear, so that you can check and memorize them as often as possible.

6.
Index marks on the flaps of the page for easy reading
We've significantly enhanced the reading function so you can prepare for the civil service English exam with just one vocabulary textbook.
The goal is to read the book at least three times, but the amount of vocabulary memorized will vary depending on the number of times you read it, allowing you to learn vocabulary solidly.
The textbook has a color-coded index on the flaps to help you study 50 words per day for the first reading, 150 words per day for the second reading, and 250 words per day for the third reading.
