RadioTelephone Tutor is a tutor program that helps you study for the FCC GROL License, plus the Ship Radar Endorsement License. Often times, test questions are worded in ways; that fool you. RadioTelephone Tutor drills you on the questions you don't know; till you know the answers backwards and forwards. Drills on missed questions, can take entire question pools in straight, or random order.
RadioTelephone Tutor creates a practice test; which represents what you would be given in a real exam. (Uses DosBox in addition to the pure windows version and dos version. The reason for this is to work around some computer's problems with their graphic cards and drivers.)
