How to insert timer to record user response time for quiz questions

Hi,

How can I add a timer to record the response time for quiz questions? also I would like the total time recorded to answer one quiz (a total of 10 questions) to be visible on the last screen. Anyone could help with this?

I would look at the Timer blocks to record the time. Initialize a new variable to keep track of time. Set the timer to fire every second, and when the timer fires, add one to the new variable. That variable now holds how long it has been.
