Ratings and reviews

After having recently passed my 500 ton after a couple of attempts spanning over multiple years, I can say with the utmost certainty that this app is one of the only things that you really need to prepare for a uscg national license exams. The creator of Sea Trials is dedicated, and you can tell that they truly care about their product. Will continue to pay for my subscription just to support such an invaluable resource for any mariner looking to upgrade their license.

new overhaul has many issues, many illustrations don't load, the font is too large so you have to do a lot of scrolling through long questions and sometimes you can't even read the answers if they're long-winded. practice tests aren't functioning properly. miss the old version. working fine through desktop browser though. hopefully they get it fixed soon as I can see this overhaul does have nice potential, they just released it half-baked.

Best CG exam study tool in my opinion. The support team is prompt with fixing any issues. I've used the app daily for months on end prepping for my exams and I've found it to be the easiest to use. Highly recommend!
