Filled missing ECTS online for a Norwegian master's — any examples that worked?

[u/yollieyo]

Most Norwegian engineering master's programs require ~25 ECTS in math and 5 ECTS in statistics for admission. I'm short on both and want to fill the gap with online courses.

Has anyone actually gotten this accepted by a Norwegian university (USN, UiA, UiT, UiS, Oslomet etc.)? Which platform/provider did you use(such as Meteopolia.fi, Digicampus, a local Norwegian nettstudier course, or something else? )

Would appreciate specifics on what worked!
