Last Monday at 9 AM, 13 laptops showed up in my stats at once.
A school class in Slovakia used mathedu.online for 2 hours: unit conversions, grade 5. ~500 problems per kid, 95 % correct. Nobody told me. I don't know which school it was, and with cookieless analytics I never will.
So this weekend I shipped classes for teachers: – printed tests with a per-student code + QR – enter paper results as ✓ / ✗, the site does the math – gradebook export (CSV) – invite parents with one link
