Use a Google Sheet as the single source of truth. When you edit a column, a no-code scenario updates the calendar event title, location, and reminders. Missed entries trigger alerts, while recurring patterns clone future weeks, preventing manual duplication and late switches that break your rhythm.
When a class is added, dropped, or moved by your registrar, a webhook can refresh your private class dashboard and calendar notes instantly. Attachments like slides or reading lists are auto-linked to sessions, saving clicks, reducing inbox clutter, and helping you arrive already prepared, not scrambling.
Create a QR code that opens a short form; submissions write to a sheet and timestamp automatically. A filter checks delays, updates participation points, and emails gentle nudges. You get a shareable attendance history without spreadsheets marathons, plus trend insights that actually inform coaching conversations.
