At least the part about the "Prussian system" is not only untrue but completely non-sense.
Prussia, indeed, was one of the countries in the world to introduce free and generally compulsory primary education, consisting of an eight-year course of basic education, in 1717.
But elsewhere, in nearly all other German countries, there had been a good educational system as well. (Around 1650, we had in my native town one compulsory primary school - run by the town - and two 'high schools'; about 2,000 inhabitants at that time and not situated in Prussia.)
There are several books -in English- about the education in late medieval times (1250 - 1500) in Germany. You only have to read the blurbs, gunga, ....
