Prepare a decision table that accurately reflects the following course grading policy:
A student may receive a final course grade of A, B, C, D Or F. In deriving the student’s final course grade, the instructorfirst determines an initial or tentative grade for the student,which is determined in the following manner:
A student who has scored a total of no lower that 90 percent on thefirst three assignments and exams and received a score no lowerthan 70 percent on the fourth assignment will receive an initialgrade of A for the course. A student who has scored a total lower than 90 percent but no lower than 80 percent on the first three assignments and exams and received a score no lower than 70 percenton the fourth assignments will receive an initial grade of B forthe course. A student who has scored a total lower than 80 percentbut no lower than 70 percent on the first three assignments andexams and received a score no lower than 70 percent on the fourth assignment will receive an initial grade of C for the course. Astudent who has scored a total lower than 70 percent but no lowerthan 60 percent on the first three assignments and exams andreceived a score no lower than 70 percent on the fourth assignment will received an initial grade of D for the course. A student whohas scored a total lower than 60 percent on the first three assignments and exams or received a score lower than 70 percent on the fourth assignment will receive an initial and final grade of F for the course. Once the instructor has determined the initialcourse grade for the student, the final course grade will be determined. The student’s final course grade will be the sameas his or her initial course grade if not more than three class periods during the semester were missed. Otherwise the student’s final course grade will be one letter gradelower than his or her initial course grade (for example, an A willbecome a B).
