Scenario: A friend has asked you to design a simple grade book program. He would like to create some calculations that can be used for any test given to students. This program should generate percentage scores for each student (given the number of correct answers and the total number of questions on the test). He would also like the program to calculate the class average of the percentage scores and identify the minimum and maximum scores for the class.

Write the pseudo code for this electronic grade book. For those who are ready for a little more advanced concepts, have your pseudo code determine the letter grade for each student (90+ = a, 80+ = b, 70+ = c, 64+ = d, lower than 64 = f).
