Being disappointed was a joke. Why would I be disappointed in someone I don’t know? Per the pass fail system you describe, that is essentially what I do. Classework is graded with daily written feedback on a 0-10 point scale with 5 points coming from attempting the assignment. I aim for a 7 because a binary scale does not represent the quality of the students’ work. In the end, it reduces yo the same binary scale regardless, but the important thing is that they receive the level of feedback they deserve. My grading policy does not effect their grades. Most of my students earn A’s.
Oh and I know fully well how these sites work. I have to contact them frequently for violation of copyright.
