LAPWARE is a long-standing, well-regarded USCG license study program covering deck and engine credentials all the way up the ladder. CaptainsGround is a free, citation-backed drilling tool. They aim at overlapping candidates from different angles.
TL;DR
LAPWARE: paid access billed in 31-day blocks (about $150 for the first month including a $50 setup fee, then $100 per 31 days), deck and engine sold separately, deep coverage and a strong professional reputation, but a dated web interface. CaptainsGround: free to start, every answer cited to a public source, modern web UI, with AB and QMED tracks alongside OUPV/Master.

LAPWARE has the deeper catalog and the track record for higher-level engine and deck licenses, and if you want its bank you'll pay per 31-day block for deck and engine separately. If you want a free, modern, citation-backed way to drill AB, QMED, or a captain's license — and to verify every answer against the rule it tests — CaptainsGround is the lighter-weight fit, and many candidates use both.
