I absolutely love the ASA cd rom software. HUGE FAN! The last 2 test I have taken using it for my instrument and my commercial I scored 92, and 98. You can use the the books which I did as well, but the software worked excellent for me because it kept a tally of what questions I missed every time I took the test so I can review them as much as possible. Godd luck on the test. Also, you can try www.webexams.com which allows you take the random test online for free.
