Our approach
We build each calculator around a specific job: calculate a current grade, apply weights, plan a final, score one test, or grade a stack of papers.
Clarity
Inputs use plain language, formulas are shown, and assumptions are explained.
Accuracy
Calculators are tested against known examples and boundary cases before release. The site does not replace your syllabus or instructor's grading policy.
Performance
The site is designed static-first with lightweight client-side calculation, minimal third-party code, responsive layouts, and no account requirement for core tools.
