Our school year is 4 quarters long (students get a grade and report card each quarter), and 2 semesters total (each semester is 2 quarters, semester grade awarded at the end of 2nd and 4th quarters).
We have the following set up to calculate a semester grade as the average of two quarter grades:

Just wondering what's the difference between Report Card Grade or Grade Book Cumulative? Does it matter which one you use (or what if you input something for both)?
Thanks!
