OP is trying to get to grips with VB.Net and 'needed' something like an array of Collections. I was looking at this thread http://www.vbforums.com/showthread.p...85#post4266985 and was trying to work out how I'd store the Questions and Answers. Came to the conclusion that a List for each subject would work. (as would a UDT Array, nD Array and many other things that I haven't discovered yet no doubt) but as I hadn't looked at Lists before thought I'd give it a try.
