Changing existing grade scheme colors

Yes. You can edit the scheme by going into the grades tool and clicking on the schemes tab. Then click on the name of the scheme you want to edit. Then make the changes and save them.

If it is a scheme created at the MyHome level by an admin, they will have to make the change from the grade schemes option in the admin tools.

This is my training video on grade schemes: https://www.youtube.com/watch?v=2LCm4hwPEVI&list=PLbK09G5ftAjWcjaGjLYyXyfv5RiBG59DF&index=26

If the change isn't something the whole institution needs, you can click on the more actions dropdown menu. Then choose the Copy option. Then select the scheme you want to copy with the circle option on the left. Then copy it.

Then you can make changes to that copy and make it the course default.

What if I cannot update the Mac OS due to the iTunes Error code 590624 that has occurred in it? What can be the alternative method apart from fixing it?
