I’m self-studying for the 500. Don’t have the time n cash to spend at a prep class so here’s what I’m doing.
I bought the 500-1600 GT prep course flash drive through Mariner advancement http://www.marineradvancement.com/ It is OK, puts the test in front of you. Illustration are not eh greatest quality. Tide current publications are in complete. so…
I went to Amazon and bought…a cheap Bowditch - new paperback reprint of the 2011 edition I believe
And the publications at this link…http://www.mmts.com/publications/deck-publications/ Deck adn stability questions worked out and terrestrial nav questions worked out and the tide current tables.
I also have the 3 training charst I purchased for 20 bucks from sea school.
Here is a site to download the entire cfrs on pdf. very helpful on tricky deck gen questions about lifejackets and unlicensed towing vessels, etc.
Anyhow, I’m working hard on studying, focusing on the 90%er material, and feeling that it is not gonna be as hard as I thought.
