Kundukisa, I am interested in student learning - not student grades. Socrates would ask questions and I suspect his method of grading was more aligned with "yeah, they got it" or "no, they've missed it". I am not a fan of EC and choose not to use it. What good is a higher grade if higher learning has not accompanied it? I say, if it's important to learning the material, it should be included in the regular assignments. No EC. My opinion - my bias. Other opinions may vary, and that's OK. Barry Westling
