QSKY Presents:

The Digital Novice Quiz

Are You A Digital Novice?

Here's a quiz to find out if you qualify as a digital novice. The idea here is to learn and have fun. When you have completed the test, you'll be able to check the results instantly. A message will also be sent to Jim, K9EI so that he can verify the results. If you score 80 percent or better, an e-mail will be sent to you with the URL of your full-color Digital Novice certificate. So be sure to enter a valid e-mail address. You'll be able to download the certificate and print it if you like. How's that for instant gratification?
