Conversion Methodology

Converting between raw scores, percentages, and letter grades depends on whether your school utilizes a 10-point scale (standard in the United States) or a 7-point scale. Our tools default to the official 10-point rubric, ensuring exact alignment with collegiate admissions benchmarks.
