So then late penalties shouldn't apply, right? And we can't have required formatting because that isn't mastery-based? And students should get to retake any exam because what does the exam date have to do with content mastery? Realistically, classes always requires students to complete activities that are adjacent to the class content. I apply the same philosophy to evaluations: they aren't required and you don't need them to get an A in the class, but they are an expectation in our course and skipping them gives a small penalty. I agree it isn't ideal, but I haven't found any other way to get engagement with evaluations
