Developed by professionals at the Sogang Korean Language Education Center, Sogang Korean provides a comprehensive approach to Korean communication and contemporary culture. The four language skills–speaking, listening, reading, and writing–are connected by a common learning objective in each lesson, enabling learners to practice, extend, and apply their knowledge and skills.

The Sogang Korean 4B Student Book is designed to be used after completion of Level 4A. Authentic dialogues help students grasp important Korean grammar structures and vocabulary, while appealing illustrations and frequent comprehension checks support their understanding. In each lesson, students are encouraged to reinforce what they have learned through a variety of both controlled and free conversation activities.

To facilitate independent study, the Student Book is accompanied by a separate grammar booklet with English explanations, scripts for each CD, and a glossary of terms. The CD contains 16 listening exercises, pronunciation exercises, dialogues, recordings of the lesson readings, and a Korean song. The 4B Workbook provides exercises for additional review and practice. The 4B Student Book and corresponding Workbook are intended to cover 75-100 hours of instruction.
