Final exams in my course are optional, if a student is satisfied with their current grade then they can choose not to take the final and their current grade will be their final grade. The final, if taken, is to replace the lowest mid-term exam score, regardless of whether it improves their grade or not. (If I have to spend the extra time to grade it, then it WILL count.) So I've been trying to set this up using the assignment rules available, I know I can drop a low score and assign the final as a never-drop score, but how does this affect calculated grades for students who opt-out of the final? Will it also drop a low score for them?
