I want get a refund. The e-version text-book is not acceptable quality at all. I am Korean and supposed to teach Korean to my friends but, I cannot teach with this kind of book at all. Please help me to get refund.
I have finally completed this entire book. It is well written and easy to learn from. Every grammar point a beginning student would need is well explained and accompanied by appropriate lessons to help drive the concept home. This book also has a workbook to further your learning experience.
