Thank you for your question and also for your support.
I’m not quite sure what you mean with regards to certification question patterns. I have a series of courses called Building Structures in German, and they deal quite a lot with different ways to ask questions in German, is that what you mean?
As for German films and songs, I shall make a collection for you and then write it up into a blog post. I’ll let you know once I’ve posted it and share it with you.
Hope that helps,
