Quiz

Greetings all !

I have gone through the process of using backup/restore for courses and need a suggestion about certain policies.

I created a master course with couple of quizes. Then I backed it up and use the backup .zip to create new courses (copies of master). Now down the line if I find that certain questions is phrased incorrectly and if I modify it then, then in that case the change will reflect in all previous quizes as well since they all refer to same question record in DB. I want to avoid that as I need to know exactly which exam was taken by students in previous batches. Is there a way so taht the modifications will apply only to future quizes ??

Thanks in advance for your inputs - Ani.
