Ateneo QPI Calculator

The story

It started with the what-if game. “What do I need on the final to get a B+?” “If I get an A here and a C+ there, what will my QPI be?” I was doing this constantly.

The existing calculator was fine for one quick calculation, but playing with scenarios meant re-entering every course and unit each time you tweaked one grade. I wanted something more like a dashboard: courses that stay put, and outcomes that are easy to predict.

So I built it as a side project for myself. I gathered the curriculum data so auto-fill would be accurate and focused on making it clean and fast, especially on mobile.

What came of it

I shared the link with a few friends and it spread by word of mouth; I never really promoted it. The analytics told the story: 9,600+ sessions, 131,000+ interactions and the #2 Google spot for “QPI calculator.”

A good reminder that if something small keeps annoying you, a lot of other people probably feel the same way.
