GPA for Oxford College of Emory University

I have read in a few threads on this website, and on Emory Univeristy’s website that there is a GPA calculating tool for high school students to use for admissions. The website where the calculator was, is no longer available. Where could I find the moved tool? How would I go about calculating it manually?

Here is the link to the old tool: http://oxford.emory.edu/admission/gpa_calculator/

I appreciate any help. Thank you.

It used to be:
A: 90-100, 4.0
B: 80-100, 3.0
C: 70-80, 2.0
D: 60-70, 1.0
F: <60, 0.0

But there’s a new Dean of Admissions, so I’m not sure they’re using that anymore.

Thank you
