OUPV Captain's License Study Guide — a brief, focused exam prep book by Captain Mark. The Chartroom is the practice engine built alongside it.
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. Repetition is how a memorization-heavy exam gets passed — so you drill what actually needs work, not what you already know.
Adapts to You
The app finds your weak spots and drills them until you're ready. Track every topic, every session, every improvement.
What Makes a Quality Question?
A quality test question measures a student's true mastery of a specific learning objective — without relying on confusion, bias, or lucky guessing. That's the standard every question is written to. Here's what that means in practice.
Measures true mastery
Each question targets a specific learning objective and rewards genuinely understanding it — not test-taking tricks or rote pattern-matching.
No confusion
Clear, unambiguous wording, so the question measures whether you know the material — not whether you can decode a badly written sentence.
No bias
Nothing in the phrasing or setup tips the answer or quietly favors one kind of test-taker over another. The question is fair.
No lucky guessing
Every distractor is plausible and the correct answer is never given away, so a lucky guess can’t stand in for genuinely knowing it.
…and every one is tied to a USCG rule
On top of that standard, every Chartroom question is anchored to the specific rule it tests — the COLREGS rule or CFR citation behind the correct answer. You don't just learn which option is right; you learn 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.
