When you meet the standard on 32-35 assignments, you earn an A! meet the standard on 29-31 assignments = B meet the standard on 26-28 assignments = C meet the standard on 23-25 assignments = D if fewer than 23 assignments meet the standard, it will yield an F grade.
I was surprised that this course didn't follow the normal grading scale just because I assumed all courses would follow a general scale. As a student, I've always been a little afraid of rubric grading because getting feedback makes me nervous but now that I'm in the teaching field, I understand why it's important. It's important to get feedback so you know what you need to improve on so you can be your best teaching self.
