Everything You Need to Pass
Purpose-built for the USCG exam. Not a generic quiz app — a professional maritime study system.
Captain-Reviewed Explanations
Every explanation cites the specific rule it rests on and is reviewed by a USCG Licensed Captain — and corrected quickly when one needs it. You'll understand the why, not just the what.
Practice That Targets Your Weak Spots
The app tracks which topics you miss and keeps bringing them back until they stick. You drill what actually needs work — not what you already know.
Timed Exam Simulation
Full-length timed exams with a question map, flagging, and scoring that matches the real test — including the 90% Rules of the Road gate.
Every question cites the rule it tests
Not a trick question bank. Each item is written against a specific COLREGS rule or CFR section, then reviewed by a captain. You learn which option is right — and the regulation it comes from — so it holds up on exam day and on the water.

Built by Someone Who's Been There
I'm a USCG Licensed Captain with a Master's Degree in Teaching. I built The Chartroom to bring real-world experience into exam prep — each explanation citing the regulation it rests on, and explained the way I wish I'd been taught.
