  • Serious ‘XM (aka W2XM) presentsExam-Prep Jepperdee:General-Class Edition
  • If you are viewing this on , you are looking at a non-interactive preview of a game,which, once downloaded as a PowerPoint file, is an educational andentertaining 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. Eachcategory covers a chapter in the General Class License Manual, and eachquestion is from General Class Question Pool Effective 7/1/11 – 6/30/15. The two game boards have questions of equal point value, andeach one has exactly one Daily Double. This permits a fair competitionbetween the players on different boards. Make up your own rules! SFJstands for semi-final Jepperdee and FJ stands for final jepperdee. The entire file can be downloaded from this site as an interactiveand playable game. You may also receive this file by e-mail bycontacting the author at W2XM@ARRL.NET. Doing so will put you onW2XM’s e-mail list of game users (…and you will receive a schematic ofthe Serious ‘XM Exam-prep Jepperdee hardware set).
