Howdy doody Excelers,

I have been struggling all morning with what I assume is a simple problem to some of you. Everyday I have quizzes prepared, and the length of quizzes often changes. I am trying to create a spreadsheet which can automatically calculate score, given the total # of questions (variable), and the number of incorrect answers.

Specifically, I have
-A column for question # (A:A).
-On the right hand side, I have a column of questions (hidden).
-Column B is for when a student answers incorrectly, I note "Incorrect."
-Columns C and D indicate either -1 for incorrect, or +1 for correct, using a simple IF function. Columns E-F

Question:
Can anyone think of a function to determine the Correct/Total score, as displayed in E-G? Remember, the quiz lengths change on a daily basis. You may begin writing your answers...NOW! ;D
