Is it possible to switch from primary school teaching to secondary school teaching (secondary level 2)?
If you take German and everyday culture and health, would you have to replace the second subject with another subject relevant to high school? Is it possible to transfer to a higher semester if you are currently completing your bachelor's degree in German? Will this be credited? Even if you have to take a new subject?
The two degree programs are not identical, so it will likely be up to the university to decide on a case-by-case basis which coursework from the first degree can be credited. You can probably get preliminary information from the central student advisory service at the respective university.
