L2 German is sufficient to study in Germany

For those students, who finished their European Baccalaureate and consider to study in Germany: a BAC-certificate, which includes a successfully completed examination in German as either the first language (L1) or the second language (L2), is recognised as proof of the German language skills required for admission to university studies in Germany (Source: Decision of the Assembly of ministers of education of the German states (KMK), 14.6.2018).

Probably this is the same for other countries as well, but needs to be verified first. If you know more about BAC-language requirements in other EU countries please leave a comment below.
