Korean Grammar Workbook Suggestion
Can anyone suggest a Korean grammar workbook with mixed grammar points exercises?

At the moment I really like 'Korean Grammar in Use: Beginning to Early Intermediate' for explanations but I feel the practice is scarce and obvious, because you can only use the grammar points you learned in the current lesson.

Answer

I recommend "INTERMEDIATE KOREAN : A GRAMMAR AND WORKBOOK" by Andrew Sangpil Byon

If you send me a message, I will send you the pdf file.
