There are a number of Ham Radio License practice tests available on line. My favorite is at
www.qrz.com (click on the RESOURCES tab across the blue bar at the top of the page, then click on PRACTICE AMATEUR RADIO EXAMS then click on which test you want to practice). The following link should take you there.

Anyway, I took the EXTRA test exam this morning and only answered 80% of the questions correctly. Give it a try and post how you did. I am amazed at how much the content has changed since I passed the extra exam back in 1998.
73 and good luck
