You're writing a cgi-script to give a quiz?
Sorry to be a wet blanket here, but have you considered what happens when:
- A quiz taker clicks the reload button, over and over?
- A quiz taker clicks the back button (maybe more than once), then submits a new answer?
- A quiz taker clicks the back button, then the reload button?
If any of these possibilities give you trouble, consider using CGI:Session to maintain state, and save state data server-side in a database like mysql.
ps: if you think this is easy - you're doing something horribly wrong.
