Description

This is the full question pool for the ham radio extra class exam, effective July 2020-June 2024. You can view the original, official NCVEC document at Public Release 2020-2024 Extra Class Pool. This deck includes all images included in the original release. The extra class exam is the third in a series of three exams:
  1. Technician
  2. General
  3. Extra
There are study decks available for all three tests. This is the question pool to use if you plan on taking your test between July 2020 and June 2024. Don't use an expired question pool if you plan on sitting your exam within this range. Don't use this question pool if you plan on sitting your exam after June 2024. I intend to make new decks for each question pool about two months before that test goes live. But if I seem to have abandoned that project, you can use my question processor code at https://github.com/JASchilz/Ham2Anki.
