A HAREC certificate allows you to apply for the highest class of amateur licence in any CEPT country. There's an opportunity to take a 40 question HAREC exam at the HAMEXPO show in Le Mans Oct. 12
The 1-hour single multiple-choice paper is the equivalent of doing the UK Foundation, Intermediate, and Advanced exams but there's less than a third of the questions and no Practical Assessments are required.
Ofcom will issue a Full M0 licence to anyone passing and getting a HAREC certificate. The only drawback with the exam is that the questions are in French.
