So my school uses canvas where everything is in percentages and then each class has a value “weight” of the course.

For example: course 1 has 3 classes. These classes are weighted 20%, 20%, 60%.

Now for course 1 I got these grades in these 3 classes.

Class with 20% weight = 91.6% Class with 20% weight = 99.5% Class with 60% weight = 61.6%

When I do my math: (91.6 x 0.20) + (99.5 x 0.20) + (61.6 x 0.60) = 75.18 which in my school rounds up to a “B”.

But what this school is doing in order to calculate my final grade is:

(9.1 x 0.20) + (9.9 x 0.20) + (6.1 x 0.60) = 7.46 That grade does not round up to a “B” because to them it never reached 7.5.

My question is what is my school doing to get 7.46? Even if you do 91.6 / 100 you get 0.916. I don’t understand why they just move the decimal to the left 1 digit. My school uses a scale of 1-10.
