Exam-Prep Jepperdee:General-Class Edition

If you are viewing this on http://www.arrl.org/studying-for-the-general-license , you are looking at a non-interactive preview of a game, which, once downloaded as a PowerPoint file, is an educational and entertaining tool designed to be used in preparation for the General-class license exam.

The game plays similarly to the way ABC-TV’s Jeopardy plays. There should be several players and a master of ceremonies. Each category covers a chapter in the General Class License Manual, and each question is from General Class Question Pool Effective 7/1/11 – 6/30/15.

The two game boards have questions of equal point value, and each one has exactly one Daily Double. This permits a fair competition between the players on different boards. Make up your own rules! SFJ stands for semi-final Jepperdee and FJ stands for final jepperdee.

The entire file can be downloaded from this site as an interactive and playable game. You may also receive this file by e-mail by contacting the author at W2XM@ARRL.NET. Doing so will put you on W2XM’s e-mail list of game users (…and you will receive a schematic of the Serious ‘XM Exam-prep Jepperdee hardware set).
