The GPA Calculator is a clean, responsive tool for computing credit-weighted GPAs. It supports multiple grading scales (4.0 and 5.0 presets), lets you add or remove courses, edit grade points directly, and computes the GPA using total grade points divided by total credits. The app can save/load your course list to the browser, export a CSV, and control display precision. It’s accessible, keyboard-friendly, and ready to drop into any static site or learning portal.
