All I want is to pose the question ... choose the answer from a choice of 4 and then be told if it's right or wrong. Not worried about scoring etc.
To be perfectly honest, I think the simple act of programmatically determining
"correct" or "incorrect" based on user input is stretching (if not flat-out breaking
—for most platforms) the capabilities of the mobi format.
Basically, giving the user a list of multiple choice answers which includes html links (that they will have
to click/tap) to a "correct" or "incorrect" page, is the best you're going to be able to accomplish. And you're probably going to need correct/incorrect pages for each
individual question if you want to include a link back to same question you were on.
I've tried Word to create an HTML file but can't seem to get that to work properly.
I'm afraid I wouldn't know how to begin to get that done with Word-produced HTML (not that you won't be able to, I just don't use Word to produce HTML).
