Some CEPT countries only have a single licence class and a single exam while others, such as the UK, require exams to be passed at different levels before a CEPT Class 1 licence is issued.
Norway has a single class of Amateur Radio license. It is thought the single 28 question exam paper, to get the equivalent of a CEPT Class 1 licence (equal to UK Full), may be the shortest of any CEPT country.
The Norwegian national society the NRRL report that a recent training course in Bergen required 12 evenings of study (total length 24 hours?) and achieved an impressive pass rate of 95%
