Yeah it costs! But you can loan money from the goverment to get the education! Everyone here has the right to studt what ever they want! My sister is studying to be a history/religion teacher, it's a five year education (and two extra if she want to be a professor or something).
She will be spending her life paying of the loans, since there is very few dorms or whatever connected to the school so she needs money for an apartment, food, internet, TV, electricity and other stuff! There are no universities here in our hometown.
I still can't find anything that says Swedish citizens pay for tuition. Seems like she is going in debt on living expenses? Does she work and go to school? I think you'd be surprised to compare the average US debt for college and the average Swedish debt.
Also I'm coming across these average 5 week vacations for jobs in Sweden. Does that seem right?
