For quite a few years there have been various versions of a teacher’s grade book spreadsheet available.
In the late 90’s I made one for a teacher. Soon there were more teachers that needed similar spreadsheets.
Then in the mid-2000s, there was one from Royce Holdeman and Scott Schultz that became quite popular. It is still a great program but because of the macros it only works on desktop spreadsheet programs.
Now another teacher’s grade book spreadsheet has been created that does away with the need for macros and does everything you need for the desktop, from web office 365, or from mobile versions on your tablet or iPad.
