My "high school" was not in the US. They don't even _have_ a GPA! No matter how it's calculated, they don't have it. They have quarterly tests(some lesser tests in between), and they have a weighted average of your scores for that particular year. You are above some number, you pass, otherwise you fail. It does not carry over to the next year. How would someone like me input anything resembling a GPA? Also, it was a long while ago. I would not be surprised to hear that companies that ask these questions also have ageist policies.
