I am also there and I didn't pay any monies anywhere for university(unless you mean fancy private university?). All state universities are free and we only paid some misely amount every 6 months for the city-ticket(free access to all public transport in the city, cool stuff). Also, state pays each child ~125/month until they are 25.
I believe you are in some different parallel universe entirely O.o

Before that, 70 euros? Where were you living, Freising?
Two external rings were around 50 euros at the time, and many students rent inside the (old) 4 inner rings, or the first external one if you study in Garching
