Pick a Date Range (Spreadsheet)
Hi Fellow Educators:
Some advice...the pick a date range is not working reliably after around 3 months or so (I sent a few bug reports), but it seems to be fine in periods of less than 3 months. So, if you are using the points as a grade determination parameter, just do it in increments of less than 3 months and everything is OK. I was using accumulated points from the beginning of the semester as a constant reference/starting point.
Good luck fellow Duolingers
