While preparing for university, I took past editions of ENEM, Brazil’s national entrance exam, as practice and logged every result.

What I built

  • A log of every practice exam: right answers per area, essay score, and how many answers I knew versus guessed.
  • A Shiny for Python dashboard on top of it: score trends per area, essay scores, two attempts of the same exam side by side, and known versus guessed per area.

My first end-to-end data project, from collecting my own data to an interactive dashboard.
