Hi,
It is possible for Swedish (and other nationalities too,
AFAIK) applicants to enroll at the UiT-program. There are already students in the latest class that are from Sweden.
The aptitude tests are approximately the same as used by the Norwegian Airforce, and you have to have studied maths and physics at least one year in secondary school. For additional info, visit
Luftfartsfag (Norwegian content).
12 new students shall be accepted for the program each semester. I guess it is "hard" to get in (there are more applicants than people being accepted..), but then again, there is no harm in applying and the worst that can happen is that you get a no. If you are qualified, and have the skills they are looking for, it is not hard, but a nice challenge. That's the point of the selection.
I also recommend applying for TFHS's MPL-program, if the school will continue to accept new students.
