In Gradarius, assignment score will be calculated as one of the following two types and it will be decided by your instructor:
Normalized Sum
Assignment score is equal to total points collected divided by the maximum points available. For example, if you have an assignment of 5 exercises of 100 points each and you have collected 425 points in total from that assignment, your final score for the assignment would be equal to 425/500= .85; that is, your score is 85/100.
Total Sum
Assignment score is equal to the total sum of the points of exercises in the assignment.
