Data Squad won first place at the ESP Medium Challenge 2026, held from 18 to 20 July 2026 in Nouakchott.
The challenge was to analyse exam results. Rather than deliver a one-off analysis, the team designed BAC Auditor: a system able to take any results file, audit it and draw its own conclusions, with built-in robustness checks.
It was this generic, reusable, tool-based approach that made the difference.
