German exam

I'm pretty busy these last weeks, since at the end of October and beginning of November I will do the KDS (Kleines Deutsches Sprachdiplom) exam, a German exam from the Goethe Institut, equivalent to Proficiency in English. I hope this will be my last German exam, there is nothing else apart from exams for language specialists, it's not my case.
And the funny question that arises is, when can I practice my German?? Yes, I live in Germany, but at work most of the tasks are done in English, and most of my colleagues are also foreigners, so we can speak either English or French, even Spanish! And outside, most of my friends are also foreigners, or Germans who speak Spanish, same situation!
Of course I can watch TV, read newspapers and, being surrounded by the language, you get a lot every day without notice, but you really have to make an effort to read, watch TV and speak German. Nowadays it's so easy to keep in touch with other places and people, to have access to international channels, newspapers, books... You can really forget that you are living abroad, not good if you want to improve the language!
Doing these exams has somehow become my only way to force myself to do so :)
