First of all, I must say that for the last 6 months I studied intermediate Korean level with my tutor and the result was very good so far. Vocabulary, grammar and listening aspects of the language improved significantly. I especially like the fact that there are lots of exercises to make sure that you understand and retain the material.
I have almost completed all the exercises in all the books at intermediate level. At this point I searched for advanced intermediate level materials and, to my surprise, found only the textbook and no workbooks, although audio materials for workbooks are available. Please let me know if there are workbooks available and where it would be possible to purchase them.
It would be nice if links to amazon or another online bookstore would be present on the site to simplify the search.
The division of levels is clear to me know, but was not so clear in the beginning. If there was a description of the structure of the whole course, it would help to plan and simplify studies.
