I have two important quizzes, weighted for 12.5% each. Students have just taken one, and they will take the other one later in the semester. My problem? The grade displayed for the quiz is NOT the grade displayed in the weighted column! This is misleading and confusing to students, who wonder why their 96 became a 93, and which one I will count. Is there some way to make one column invisible to students?
I read somewhere that it might be because I have a weighted column that is unfilled. This is unlikely: final exams, for instance, would cause problems for the whole semester before being filled in.
