Personally I would say that going to university for jazz studies is a bit of a waste. I know, praise music and follow your dreams and all, but being a jazz musician and living is even harder than just being a musician.
Folkhögskola however is a great alternative, and you're probably getting just as good an education. Our most renowned jazz school is Skurup Folkhögskola, there is some serious competition during audition.
I don't do much jazz, but there are quite a few schools. Framnäs Folkhögskola also has a good reputation, both among jazz players and pop/rock.
I just finished my first year of folkhögskola and will be enrolling next year as well.
During an audition to a FHSK, you usually pick a song or two from a list and play it with en ensemble of current students in front of a jury, usually comprised of teachers.
After that, there is some kind of a vista or jam test, the part where most people choke.
Then there's the theory test, which might weigh differently depending on the school.
Something to remember is that you don't HAVE to know complex theory as long as you're a good player. It helps knowing what you're doing, but if you were born super musical it won't matter, as long as it sounds good. I can tell you right away that you don't have to waste your time on the circle of fifths. No test I've been handed has featured it, not even the uni one. I think the circle of fifths is stupid anyway, I never learned it because I had other ways of figuring it out.
I'd recommend studying a lot of theory, especially harmonisation, and jam a lot. Recently I got the iReal Book app. It's like the Real Book, except you can make your own tracks or download others. There are options to change the style, tempo, whatever, it's super handy. EASILY worth the 150SEK.
This alternative requires you to have an Apple product, though. Get it if you got one, I think it's one of the best practice tools ever.
