Clear grade math, without pretending every school is the same.

Why the site exists

Grade calculations are often presented as a single number without the assumptions that produced it. A student may see a weighted GPA, an unweighted GPA, a semester average, and a college application GPA that are all mathematically valid under different rules. GradeHorizon makes those rules visible.

The site combines an interactive GPA planner with source-backed tutorials. The goal is not to replace a school gradebook. It is to help a visitor reproduce the arithmetic, identify the policy question that matters, and have a better conversation with a teacher, counselor, adviser, registrar, or family member.

Who operates GradeHorizon

GradeHorizon is operated by the owner of GradeHorizon.com as an independent educational web property. It is not a school, college, admission office, registrar, scholarship provider, athletics organization, or credential-evaluation service.

Editorial questions, corrections, privacy requests, and site feedback can be sent through the contact page. The public site does not require a student account and does not ask visitors to upload transcripts.

What we publish

• Calculators and planners that show the formula and the values used.
• Worked examples with credits, grade points, weights, and intermediate results.
• Policy explanations that separate common arithmetic from school-specific decisions.
• Official-source links for registrar, College Board, AAMC, LSAC, NCAA, and other specialized rules.

Editorial standards

Every guide is written for a distinct visitor question. We avoid creating separate pages for spelling variations that have the same intent. Numerical examples are checked by reversing the calculation or reconciling totals. Policy claims are attributed to the organization that controls the rule.

When a source changes, the current official source takes priority over an older GradeHorizon explanation. Our full calculation assumptions and correction process appear on the methodology page.

Funding and independence

GradeHorizon currently contains no paid placements or affiliate offers. The site may use clearly separated advertising in the future to support hosting and continued development. Advertising will not determine a calculator result, change an editorial conclusion, or be presented as navigation.

References to third-party organizations do not imply sponsorship, endorsement, or affiliation. Trademarks belong to their respective owners.
