How to Calculate if Your High School Grading Scale is Scamming You

The 92% Injustice

You live in a highly competitive school district. You study constantly and finish the semester with a 92% in AP Calculus. You check your transcript, and it says you earned a 'B' (3.0 GPA).

You go on Reddit and see a student from a different state who got a 90% in AP Calculus. Their transcript says they earned an 'A' (4.0 GPA).

How is this legal?

The 7-Point vs 10-Point Scale

Unlike other countries, the US has no national grading standard.

The 10-Point Scale (Standard): 90-100 = A, 80-89 = B, 70-79 = C.

The 7-Point Scale (Brutal): 93-100 = A, 85-92 = B, 75-84 = C.

If your high school uses a 7-point scale, they are actively scamming you out of GPA points. They usually do this under the guise of "maintaining rigorous academic standards," but all it actually does is make their students look mathematically inferior to students from 10-point scale schools.

The College Admissions Fix

If you are trapped in a 7-point scale school, do not panic.

When you apply to college, your guidance counselor sends a High School Profile. This document explicitly states your school's grading scale. When your transcript arrives at an admissions office (like the University of Michigan), they do not just look at your 3.0. They look at the Profile, realize your school is using a brutal scale, and recalculate your GPA using their own standard 10-point baseline.

Your 92% 'B' will be translated back into an 'A' inside their computer system.

The Exception: Smaller, less-selective colleges (or automated scholarship programs) often do not have the staff to recalculate grades. They might just look at your raw 3.0 and deny you a scholarship. If this happens, you must physically call their financial aid office and explain your school's grading scale.
