There are several online locations that can assist anyone interested in learning amateur radio communications and help them practice for the exam of their choice.

The ARRL offers an online resource that allows users to take randomly generated practice exams using questions from the actual FCC examination question pool. ARRL Exam Review for Ham Radio™ is free, and users do not need to be ARRL members. The only requirement is that users must first set up a site login (this is a different and separate login from your ARRL website user registration).

ARRL Exam Review includes all of the questions for all three of the current FCC exam pools and provides different review options, so you can choose to review by chapter of the ARRL study manual or by question pool topic.  Short explanations are provided to help you understand the correct answer.  The software also provides the option to produce—and print—as many practice exams as you would like.
