[ About Workbook ]
This workbook is ideal for honing communication skills in Korean. 
Students can use this book to review lessons at home and practice the speaking, listening, reading, and writing skills taught in the textbook. 
In the work books you test the knowledge you’ve gotten from the student books through different types of excercises.
For instance matching words with the correct picture, completing sentences with the correct words, conjugating verbs, and rewriting sentences from one formality level to another.
Each chapter ends with a listening exercise and a dictation exercise.
At the very end of each chapter you find a little piece of Korean culture explained.
