Hi Captain Lee

        I just took my 500 ton master license, but did not do well. I've been studying with a study guide by Captain Joe. His web site is www.uscgexam.com. Is there any other study guides that could help me more to try to understand what I am reading. Thank you for your time.

The Murphy books are good. Taking a prep course also gets you in the right frame of mind.
