hi has it been possible to visualize the hours spent in exercises since the beginning ?
Thank you in advance
A really rough way to gauge how much time you've spent? Create a classroom and invite yourself as a student to the classroom. On the individual student page you can view an activity log, you can cut and paste this into a spreadsheet. I did mine and with a bit of messing about I got an answer of 84 hours. This would mean per lesson, per test or per practice I took 9 minutes on average.
This is, however, only a rough way. The accuracy of the result depends on how you do the lessons. You'll only get one log as per the classroom language. The activity log only gives one timestamp per event. I made an assumption that the difference between each event would be time spent on learning. I eliminated some higher values and negative differences. The negative differences would occur when the dates changed. When I didn't have a value then I used an average from the previous couple of lessons.
