## What is CRR?

Prepare for your marine radio certificate (CRR) and pass on the first try.

• Offline handbook: distress (MAYDAY/PAN PAN), DSC procedures, VHF channels & frequencies, phonetic alphabet, Q-code…
• Targeted practice: spot your weak theme and drill it.
• Real-condition mock exams: timer, no correction until the end, detailed score.
• Honest tracking: your success rate is computed from exams you actually took — never a promise.
