ClassCheck, Excel and the grade book
Three ways to keep grades. The difference is where the list lives, and whether classwork, tests and the grade proposal sit in the same table.
Excel
The file sits on your own computer. There is no encryption in the browser and no way to share a subject with colleagues.
Grade book
The book is paper. Classwork and tests are written in by hand. The table does not calculate a grade proposal.
ClassCheck
Classwork, tests and the grade proposal sit in one table. Names are encrypted in the browser before they reach the server. Subjects can be shared with colleagues. Nothing to install.
