Controls for an online quiz

Hi,
I'm new to ASP.NET. I need to develop a quiz application in ASP.NET/C#.
The requirements are:
1. Questions are read from an XML file (or a database, but right now
i'm reluctant about that)
2. A table (or other structure) with two columns and whatever number of
rows
a) first column filled with DropDownLists corresponding to
b) questions in second column
3. DropDownList contains {0,1,2,3,4,5}, none of the items is selected
by default
4. If user doesn't select any or one of the DropDownList items for the
corresponding questions and presses "Calculate Score" button, that
question(s) (text or background field) get(s) highlighted.

What are the best controls to do this with? Could somebody point me in
the right direction?
Thanks a lot!
