Hi Cristian: Each teacher and school will choose how it will address EC. For me, I feel it artificially raises grades, contributes little to learning, can be veiewed by students as unfair, and students can become expectatnt in subsequent classes to receiving EC. Over the years, I've had more bad experiences that good, so I just choose not to give it, period. Students know that at the beginning of the course so there are no misunderstandings, and it's also stated in the course syllabus. Regards, Barry
