ARRL has launched a new online resource that allows users to take randomly generated practice exams using questions from the actual examination question pool. Known as ARRL Exam Review for Ham Radio, the service is now available at http://www.arrl.org/examreview.
The new service is free; users are only required setup a site login. (Note that this is a different and separate login than the ARRL website user registration.) Users do not need to be ARRL members.
