Project overview
Professor Karen Reynolds teaches calculus at High Desert University in Tempe, Arizona. The class has 220 students who are distributed among dozens of sections and discussion groups. Professor Reynolds wants to use Excel to determine the appropriate cutoff points for her grading curve. Generally, she wants to set the cutoff points so that the following distribution of grades is observed in the student body: F 5%

D 10%
C 35%
B 35%
A 15%
Professor Reynolds has five possible grading curves. For example, in Grading Curve 1, she will assign As to test scores from 80 to 100. She wants you to evaluate each grading curve scenario and determine which one results in a distribution of grades closest to her proposed distribution. After you choose which of the five scenarios fits the data the best, she wants you to use Solver to determine whether there is a grading curve that is even closer to the desired distribution of grades.
