Great way to study   
by msturg

Great interface with the rules. Learn the rules, test and retest until you get it right. Aced my rules exam (100%) thanks to this app.

Great!!!!!!

If you are getting ready to test or upgrade its great to see how far you are off. Having it on the phone and can do a few questions whenever I have a couple of minutes is awesome. Better then carrying a big or small computer around with disks. In a week have already brought my score up big time. I highly recommend!!!!

Totally Amazing     
by Donald Newton

Best App ever! I used this to study for my test and ended up getting a 100% on it. The question pool are literally questions from the exams. The pictures are how you would see it on the exam too. I think what was most useful was when you got a question wrong it would site the exact part in the rules book where the answer is. Absolutely worth the money. Absolutely.

• Rules ebook with Interactive Table of contents, bookmarks, and updated Other editions online, even from USCG, include just one or the other. View / Page display as 2-page continuous to see US Inland and International side by side.

• Official statement of the US Inland Rules From the CFRs with links to get Annexes, Demarcation lines, etc.
