Every finals season I'd end up doing the same algebra on a notes app: "I have a 91% in homework (20%), 84% on the midterm (30%)... what do I need on the final (50%) to get an A-?" So I built GradeHQ to do it for me — and then kept adding to it until it became a real side project.

Live: gradehq.vercel.app

Code: github.com/yashmitb/gradecalc (MIT)

What it does

Add your courses with weighted categories (homework, midterms, final, etc.)
