I started self-studying with the help of your text & workbooks recently and it amazes me how easy and well structured the content is. However, as I am approaching the end of Intermediate 1 and will start with Intermediate 2 soon, I noticed how there isn't yet a answer key for this book (as well as for the advanced editions). Quit frankly, it would impossible for me to study without them as I don't have a teacher.
I'm not sure if this is the correct channel to request these answer keys but I hope I will get a reaction nonetheless.
Kind regards from The Netherlands,
