What is educalcdb?

EduCalcDb is a suite of free calculators for AP exam score estimates, curved grades, weighted course totals, and semester GPA checks. Every calculation runs in the browser, and official raw-score boundaries are not published.

What educalcdb does

AP exam tools estimate a weighted composite from multiple-choice and free-response points. Grade tools apply a curve to a raw score, compare a result with a bell curve, or total a weighted class grade. GPA tools turn courses, credits, and letter grades into a semester or cumulative GPA. Thresholds are editable so you can match a class or exam. The about page says the tools give estimates and are study aids rather than official results.

Who educalcdb is for

The calculators are aimed at students working on AP exam composites, curved or weighted class grades, and semester or cumulative GPA.

How educalcdb works

Open one calculator, type numbers, and the result updates in the browser. Nothing is uploaded, and grades never touch a server. When you type a score or change a slider, the math runs on the device. AP score cutoffs and grading curves vary by exam year and by instructor. The about page says official raw-score boundaries are not published, so the tools are study aids with editable thresholds.
