These grade calculators are programmed to calculate the letter grades using the NOHS 12 point scale. The exam exemption calculator is based on an average of both quarters being a solid B or better. If exempt, the Exam is the average of the 2 quarter grades.

The Semester Grade calculator calculates the weighted semester grade as defined in the student handbook. If a student does not pass 2 of 3 grade opportunities, it catches that and returns an "F" grade.
