Sec.  13.215   Question pools.

   The question pool for each written examination element will be composed of
   questions acceptable to the FCC. Each question pool must contain at least 5
   times the number of questions required for a single examination. The FCC
   will issue public announcements detailing the questions in the pool for each
   element. COLEMs must use only the most recent question pool made available
   to  the public when preparing a question set for a written examination
   element.
