The online HAM testing site I used:
Great site for practice, reading the questions and answers:
Another excellent source providing questions/answers/explanations:
- https://hamstudy.org/ (croud sourced explanations?)
Good reading material:
Ham Radio Prep is where I started and found it very useful. The instructional format for each section is video, followed by self-reading the same content and studying diagrams, and finally a practice test. I augmented the material with online resources, reading from ARRL books, and watching lots of YouTube videos.
The ARRL provides online practice tests also although I prefer hamexam.org for stats tracking and the weighted selection of questions. And I prefer hamstudy.org for the answer descriptions so I can understand the reasoning and methodology behind the answers.
The question pools are published here by NCVEC:
The question pools in text/json formats:
