About the tool (excerpt from the public listing)
CaptainsGround is an independent preparation tool for USCG (United States Coast Guard) captain exams. It is based on federal resources in the public domain to build a question bank, including 33/46 CFR, COLREGs, Inland Rules, NGA Bowditch, and USCG manuals. The product is positioned to help serious mariners truly understand the exam rules rather than simply memorize them. It is currently in the early access phase and is completely free. A paid tier will be introduced later, and early users can enjoy discounts. The main advantages are that all answers have authoritative citation sources, the mock exams are in the same format as the NMC, and it has an adaptive learning plan and the FSRS 4 spaced repetition system, which can effectively improve the efficiency of exam preparation.
