Coast Guard Exams: USCG Prep

Coast Guard Exams is the most comprehensive USCG exam prep app available. Study for every deck and engine certification with 31,500+ practice questions across 57 endorsement modules, powered by AI explanations that help you understand the material -- not just memorize answers.

Whether you are working toward your first captain license, preparing for a deck officer exam, or upgrading existing credentials, Coast Guard Exams covers every USCG exam category in one app.

31,500+ USCG PRACTICE QUESTIONS

The largest USCG question bank available on Android. Every question is based on publicly available USCG exam materials across all exam categories -- deck general, engine general, navigation general, navigation rules, rules of the road, stability, cargo, seamanship, and more.

57 ENDORSEMENT MODULES -- DECK AND ENGINE

Study for specific endorsements rather than drilling a single generic question pool. Coast Guard Exams organizes all 31,500+ questions into 57 focused modules covering both Deck and Engine licensing tracks. No other USCG exam app offers this level of granularity. Switch between modules as your exam schedule demands.

AI-POWERED EXPLANATIONS

Every question comes with an AI-generated explanation. When you answer incorrectly, you get a clear, contextual explanation of why the correct answer is right -- not just the answer key. AI explanations accelerate understanding of complex maritime concepts like stability calculations, Rules of the Road scenarios, and engine system principles.

CUSTOMIZABLE EXAM MODES

Practice the way that suits your learning style:

- Study Mode: Immediate feedback on every question

- Exam Simulation: Timed sessions that mirror the real USCG exam format

- Module Focus: Drill a single endorsement module until you master it

- Wrong-Answer Review: Revisit every question you have missed

PROGRESS TRACKING

Know exactly where you stand before exam day. Detailed performance dashboards show your score history across all modules, highlight weak areas, and track your improvement over time. Set a passing score target and watch your progress toward it.
