: SO??????? That does not imply that those chosen languages are official. For example, in Romania you can study and take graduation exams at least in Hungarian, German, Russian, Ukrainian (and possibly others). This does not mean those languages are official in any ways. In case it is still not clear, here is a better example: there are I believe 23 official languages in the EU, and Russian in not one of them. Nevertheless, some countries do allow for education in Russian.
