『Proper Korean 1 Workbook』 is a supplementary textbook for 『Proper Korean 1』 and was designed to allow learners to check and confirm whether they have sufficiently understood the contents of each lesson, either with the instructor or on their own.
『Proper Korean 1 Workbook』 is composed of 15 lessons and an ‘appendix’, just like 『Proper Korean 1』, and each lesson is in the order of ‘Vocabulary’, ‘Grammar’, and ‘Activities’.
