Right then, for those who are interested in this sort of thing, I have written a detailed tutorial on how to build a quiz in AS3.
You can access the tutorial here:
This tutorial also shows a practical way to read data from an XML file into a quiz. It would make a good hands-on project for someone who knows a tiny bit of flash but wants to learn more.
The source files are all there, so anyone who wants to 'help themselves' can go ahead. Feel free.
Ciao for now.
