The courses
Choose what you’re studying for
Structured theory courses sharing one pool of lessons, trainers and live worked examples — progress follows you between them. Syllabus mappings are factual; nothing here is affiliated with or endorsed by the RYA, and certificates always need an invigilated exam — we get you ready for it. Your revision book works across every course, and the Ask-the-tutor button on every lesson answers from the courses themselves, sources linked. Four courses are free; the rest are one honest payment.
