Thanks for your replies, everyone. I appreciate it and am seeing how diverse ehe process is. . I think alot has to do with time.
The ones that responded are almost all grading every 9 weeks.( only 8 replies so far) I thought it was more common to grade bi-semester. Was I wrong on this? Are there any of you who still grade twice a year? Can anybody offer a rationale for grading every nine weeks or for grading twice a year??
