Example of Final (Numerical) Grade calculation

Consider a student that has the following grades in COS 240:

Component Grade Equivalent Percentage Grade
PS1 25/40 62.5%
PS2 36/40 90%
PS3 39/40 97.5%
PS4 30/40 75%
PS5 34/40 85%
Midterm Exam 80/100 80%
Final Exam 75/100 75%
Participation 5/5 100%

The student's Participation grade is 5/5 because the student attended all 10 precepts this semester. The student's final grade for the course is calculated as

max{ ( 0.4 * Assignment_Grade + Attendance_Grade + 0.55 * Exams_Grade ) , ( 0.4 * Assignment_Grade + 0.6 * Exams_Grade ) }

where

Assignment_Grade = ( 0.25 * 62.5 + 75 + 80 + 90 + 97.5 ) / 4.25,

Attendance_Grade = 5,

Exams_Grade = max{ ( 0.2 * 80 + 0.8 * 75 ) , ( 0.4 * 80 + 0.6 * 75 ) }.

Thus, the student's final grade in the course is 81.0558823529/100
