-> Yes, technically it's free, at least listening to a lecture and taking exams
-> doesn't cost money. People working at universities are paid out of taxpayer
-> money. You still need to buy books (which you mostly don't need to do in
-> school), which can be quite expensive, and you have to pay some amount of money
-> per semester for administrative costs (this is mostly to allow the student
-> bodies that are involved in running the university to operate - universities
-> here work a little like city-states of their own with different commisions in
-> which the students get seats as well, which is required by law). How much that
-> is depends on the university. At Bremen University, I pay about 110 Euros per
-> semester.

 And the Citizens of your Country pay Dearly in Taxes. In your case I
believe a lot of it is a "Value Added" System where the Taxes are
somewhat Hidden. you don't get the Shock of seeing the Form 1040 bottom
line like here in the United States.
