I got obscenely lucky with 2 days of reliable Internet connectivity on the boat, combined with some good study materials I found online. Repeating the study habits I last used in law school a couple decades ago, I read the study materials through once, then took a couple of practice tests; reviewed the answers, then re-read the study materials focusing on the areas in which I'd made mistakes. For the last 6 hours of study, I dispensed with the study materials and just took practice test after practice test.
The morning of the HAM test, I showed up, sat down, filled out the application form,...and made mistakes in two different spaces due to my misreading of the instructions. Not an auspicious start. If I had been giving the test, I'd have thrown me out right then.
So, I actually managed to successfully complete a second application form, and somehow was able to read and follow the instructions on the two tests themselves, completing them in succession. I knew I'd made some mistakes, especially on the second, more difficult, General exam. But in the end there were no worries - the three volunteer examiners graded the tests while all the examinees waited, and...whaddya know, I passed both tests.
Which is a much more favorable result than I ever got in law school using this study method.
