It seems that the abbreviation compoenent that is "required" to post a grade is just redundent and should be removed from having to be filled in. When I went to view an assignment on both teacher/student side - I couldn't even see the abbreviaiton that I typed into that field. The person that I'm chatting with told me "it can be as simple as a letter" so if that's the case - then why do we have to put soemthing there?
