What grade do I need on the final exam to raise my grade?

Substitute your current grade (the average with the lowest quiz grade dropped on your grade summary sheet) into the equation below.  Your current grade is 60% of your overall grade, the final will be worth 40% of your overall grade.  For the desired grade substitute 90% for an A, 80% for a B, 70% for a C, or 60% for a D.

Here's an example.  What would a student with a current grade of 78% (C+) have to score on the final to raise their grade to a B?

The student would need to score 83% on the final to raise their overall average from 78% (C) to 80% (B).

For example, what would a student, with a current grade of 85% (B),  need to score on the final exam to keep a B?
