Can I use Gradekeeper on both Mac OS X and Windows?
Gradekeeper is available for both Windows and Mac OS X and classes created on one platform can be opened on the other. The Mac OS X version of Gradekeeper can open any class that has the .grk file extension by choosing Open from the File menu. For Mac OS X, you can use Get Info in the File menu to specify that Gradekeeper should open all files with the .grk file extension. When you create classes on a Mac OS X computer, always add the .grk file extension. This tells Windows that these files should be opened using Gradekeeper.
