Grading not accurate

[rithik-c]

After selecting the University of Guelph and choosing percentages as my grade input, I provided a list of sample grades. However, the final result doesn't match the given conversion chart. In the sample screenshots below, the overall percentage average calculated is ~81 which according to the conversion chart should equate to near an A- grade and ~3.7 GPA but instead it shows B grade and ~3.2 GPA

I don't know if it's correct but he evaluates the GPA value for each class and averages them. So if I get an 80 and a 100 in two classes, the average is 90% but he averages the 3.7 (from the class you got an 80 in) and a 4.0 (from the class you got a 100 in) for a GPA of 3.85. I'm not sure whether Guelph determines your GPA by which range your cumulative average falls into or not. You'd have to ask.
