Is studying in Germany really free?

That's not entirely correct. For example, at the University of Münster you do need to pay a semester fee ("Semesterbeitrag"). Granted, this will get you a ticket for all public transport (except IC/ICE) within northrine-westphalia which is definitely worth more than what you're paying.

But yes, public university in Germany is really, really cheap.

You can also often apply to have the semester fee waived due to financial hardship or special circumstances, though I have no experience with that.

How many semester per year I wonder? Usually 2 but it could be 3. Given it is charged per semester, that is an important question. And if it is 2, for about 4k Euro per year (for public u), plus living costs, cf say with 9k pound (for most uk u but non-special subjects) plus living costs in uk, still cheaper.
