In your B2 German course you will also learn to understand complex texts and conversations. So you can now converse normally with native speakers. You can also express advantages and disadvantages on many current topics. Where do you stand on issues like emigration, poverty, gender roles, and science? In your own specialty, you can understand and participate in professional discussions yourself. You express your experiences, adventures and wishes. It’s perfectly normal for you to make mistakes. But these mistakes now rarely lead to misunderstandings.
