How do I just track time spent on Duolingo?
I'd like to simply be able to grade students on the amount of time spent on Duolingo, not on level or assignment they happen to complete. Can anyone tell me how, or if, this can be done?
Maybe if you submit an assignment to achieve XP points, it tells you the average time a student should spend to achieve a specific amount of points.
If you're using Chrome, then you can install extensions like TimeStats or Webtime Tracker
