Hi Gina,
Each teacher has to decide how run their class and be in conformance with their institutional policies. Many do not allow for EC. Some of the 'A' students may feel the teacher is being unfair. That's the last thing that any teacher wants to be labeled. In my experience, EC results in only lose-lose, so I choose to avoid it, as I feel I am not helping myself or the students by giving EC.
