Don't forget that starting next year, you will no longer be able to reapply to any Finnish universities if you have been accepted to one before. I would at least get a bachelor's degree so it will be easier to apply to universities abroad if you ever want to continue your education.
Technically speaking I haven't been accepted into one, because I cannot apply without secondary education. So I'm paying to study in one. That ought to change, come next semester. But I don't know if I want to waste two or three more years on this crap.
