How do I access my Gradekeeper account from home?
There is no such thing as a Gradekeeper “account” since Gradekeeper is not an online service. You must have the program installed on any computer you want to use it on. You must also have access to any classes you saved. You can copy your classes to a flash drive to bring with you, or save them online using MobileMe from Apple or a service like Inbox that provides online storage.
