If you need to upload grades to another grading system, or if you simply want to view your students' grades in a spreadsheet, you can download the information -- class by class -- to your computer. Here's how.
Log in to your teacher account.
Select a class. Then, note the Download box on the top right.
Click the link to download a CSV (comma-separated value) file to your computer.
Once downloaded, this file can be opened with Microsoft Excel or other similar program.
