No CS teacher in my federal state since the teaching plan absolutely sucks ass.
Basically it attempts to teach you java without actually explaining it.
So people now know how algorithm XY works and looks in java, but are unable to differentiate between a float and an int.

My CS teacher is awesome tho in the regard that he single-handedly advanced our school digitally by about 15 years.
We now have tablet classes, 3D printers, more CS courses for lower grades etc. etc.
You get the picture.
