Canadian Marks To GPA

I have been trying to do my research but I have come across different things. I was wondering how to calculate my gpa from my grade percentages. I heard that US Universities add around 7-10% to your mark. Do US universities look at Canadian marks as being better than US marks? I right now average an 87 and I was just curious what that might be in GPA and what types of school I would be competetive for in the US with that mark.

I’m not sure how it is, definitively. I definitely have heard that the admissions offices will inflate Canadian marks.
An issue with that, though, is that there is no ‘Canadian’ curriculum, the curriculum and courses vary all over Canada and while most of them are quite similar, there are a few that are behind. So if American admissions did inflate marks, they would probably inflate/deflate depending on the specific province/territory. If you’re talking about the Ontario education, I definitely think there is some inflation for specific courses. For example, if you compared SBI4U with AP Biology, they’re essentially the same course with a few exceptions (one of the APBio chapters is actually done in SBI3U). Another example is MDM4U and AP Statistics, I think MDM4U actually covers more than AP Statistics even. Since AP courses in America tend to add points to the GPA, it would make sense that they would inflate the marks for the regular Ontario courses that correlate really well with their AP counterparts. So in essence, American colleges probably inflate the marks for specific courses depending on their difficulty compared to the American counterparts and depending on which curriculum the course is from.

This seems too good to be true, yet I’d love to believe it. Here I was thinking my ~90% average was total garbage when compared with US applicants. Could I have a shot? I am in BC if that makes a difference.
