Grades Calculator retrospective

Short Story

Every exam period at the university, I had to calculate the grades I needed to get to pass. For this, I had to look at the structure of each subject and calculate the grade counting practicals, assignments and exams.

Something like, 60% exam, 30% practicals, 10% assignments. Then the practicals had different percentages, practical 1: 10%, practical 2: 9%, practical 3: 11%.

I spent too much time and preferred to have an easier way to do it... So I created calculators where you can specify the structure of each subject, add your grades and see what minimum grade you needed to get to pass.

I shared it with all my friends and people used it.

Promotion

A year later after the success of Facemash UPV, I used Facemash success to promote the app.

This gave me large exposure to thousands of students around the world.

Why I Built This

I wanted to solve a problem I had, and learn Advanced Architecture development in Android.

So as soon as I didn't need the application myself, and I had learned advanced architecture development, I stopped maintaining it.

Lifespan: 3 years.
