The "Hi! Korean Series" is an integrated Korean language coursebook designed for foreign learners who are interested in Korean culture and have begun studying Korean.
The textbook incorporates the latest trends in Korean culture and offers a variety of activities to help students master the four areas of speaking, listening, reading, and writing.

It organically presents speaking, listening, reading, and writing areas while maintaining a consistent structure from beginner to advanced levels, and it is structured so that listening and reading are presented separately for each subject to increase learning concentration by area.
In particular, in the step-up course, which moves away from problem-solving-centered activities, communication skills are developed by expanding what has been learned through speaking and writing activities.
The overall composition of the 『Hi! Korean Series』 is 10 Student Books (4 beginner, 4 intermediate, and 2 advanced), which include a separate 'Grammar and Vocabulary Study Book', and 10 Workbooks (4 beginner, 4 intermediate, and 2 advanced) sold separately.

Among them, 『Hi! Korean 3B』 presents a variety of intermediate-level grammar and expressions to help intermediate learners introduce academic and career plans, problems that arise in daily life, and their own lifestyle habits, as well as acquire and understand information through media, Korean etiquette, superstitions, and more in Korean.
We have provided examples and dialogues that reflect the latest Korean culture, enabling foreign learners to learn Korean in a more practical and realistic way.
Additionally, extended practice problems are provided for learning vocabulary and expressions learned in SB, and extended practice is included for speaking, listening, and reading.
Additionally, at the end of each unit, we provide writing practice where you can write an essay on a given topic on manuscript paper so that you can practice the writing section of the actual TOPIK exam.
