I took and passed the technician's exam this morning.
For anyone else thinking of doing it, I highly recommend hamstudy.org. They have electronic "flashcards" with all of the test questions from the question pool with short explanations, as well as practice tests. As you go through the flashcards, the site tracks your progress in terms of the percentage of questions from the exam pool you've been exposed to, as well as your aptitude in individual subject areas as judged by responses. Both these measures are displayed in a neat bar chart. You can go through the flash cards randomly, or review cards related to specific subject areas separately. In addition, as you take the practice tests, results are tracked on a line graph-type chart, so you can see your progress over successive tests. And its free of charge. For me, studying the flash cards, reading some of the explanations, and then taking practice exams was much more beneficial than taking practice exams alone would have been.
