Of general education: Qualifizierender Abschluss der Mittelschule (qualified diploma of the lowest normal tier of German secondary education)
Of specific education: completed apprenticeship as a Fachinformatiker Anwendungsentwicklung (basically a software developer, but through the German apprenticeship system instead of university)
It required a lot of fighting against institutions to be allowed to get these qualifications, if it had been up to certain people, I would rot in a
workshop for the disabled today instead of writing code for an internet service provider.
