The International Certificate of Competence
This concise little book covers all that is required for both the theory and the practical tests for an ICC for Europe. It includes a small section on the inland waterways regulations (CEVNI) too.
Each area of the syllabus is covered in detail, together with revision notes and self-test questions. A very useful primer for those wishing to obtain sufficient knowledge to obtain an ICC.
