Bill - kind of a vague question (lots of vague questions tonight!).
Side note: it's interesting, seems like about half the coding questions I've seen on here are of this type-- broad, 'how do I approach the problem' types of questions. Very few seem to be specific 'how do I make strlen() work' (or whatever).
anyhow- back to the issue at hand. you've "created" a quiz. is that quiz in a database now? what is the format of the databse?
if not, you could set up the database as follows:
question, answer a, answer b, answer c, answer d, answer e, correct
where every column is a text field except 'correct', which is just a single letter indicating the correct answer (a-e).
then as you administer the quiz, you can keep a running tally of how many times the user picked the right answer (add 1 to the score) or didn't (don't change the score).
voila.
again, more specific questioning will give you more specific results. your mileage may vary.
best
