Polish universities are completely free. And yes, British universities are not free, they have recently gotten pretty expensive(£9000/year), with the exception of Scottish ones which have different rules.
"Pretty expensive" is a relative term. For comparison, one year's cost of tuition at Boston University is $53,000, plus $16,000 housing, plus $1,000 for books and supplies.
Don't forget parking. My university realized they could charge upwards of $400/semester for a spot in one of the few garages. With all the housing being built now I imagine in a few years it'll be $600+.
