I would like to see an accurate time counter. I believe my students are leaving their tab open on certain questions so that the timer continues keeping track while they work on another assignment. I have checked their progress and there are hours from starting and last time attempted.
My students are required to work on their path for 20 minutes 3X a week, but still get the minimum of 50 problems done. If you can make a timer only count the time active on a specific question and stop timing if no activity after a set amount of time, that would help.
