Is the 6500 USD tuition paid x3 each year?

Hi! Can anyone tell me whether the tuition of 6500 + 500 usd 'enrollment fee' is for each trimester/term? Or do you only need to pay twice a year?
I'm confused because here in denmark one school year = two semester, but in UNIBE's website it says that their school year is comprised of three semesters, each 16 weeks.

Thanks
