1. Write a grading program for a class with the following grading policies:

a. There are five quizzes, each graded on the basis of 10 points

b. There are five programming assignments, each graded on the basis of 100 points

c. There is two exams and one final exam, each graded on the basis of 100 points

d. There is a project graded on the basis of 100 points

e. The final exam counts for 30% of the grade, each exam counts for 20%, all the

quiz count for 10%, assignments count for 10%, and the project count for 10% of

the grade. (Do not forget to normalize the scores. They should be converted to a

percentage before they are averaged in.)

Any grade of 90 or more is an
