About GradeLogic

GradeLogic is a set of calculators for the numbers students, teachers and parents deal with every term: the score needed on a final, weighted course grades, semester and cumulative GPA, GPA scale conversions and test percentages.

What we focus on

• One tool per real task. Six calculators, each answering a different question.
• Showing the working. Every result comes with the formula, your numbers substituted in, and the assumptions behind it.
• Being straight about limits. Grading policies differ between schools. Where a result depends on a convention — a grading scale, a weighting bonus, a conversion method — we say so.
• Respecting privacy. Calculations run in your browser. There are no accounts.

What GradeLogic is not

GradeLogic isn't a school, a tutoring service or a credential evaluator, and it isn't affiliated with any institution. Results are estimates to help you plan. Your official grades and GPA are the ones your school records.
