Aanya runs the Tech Club’s event team, and in the past she had to juggle Google Forms, spreadsheets, chat messages, and manual score calculations. On event day, that meant stress, delays, and a lot of room for mistakes.

With ChaosSprint, she creates the event from a template, opens registration with one link, and schedules the challenge drops in advance. Volunteers track teams from a single dashboard, judges score on their phones, and the final ranking is calculated automatically.

The result is a smoother event for participants and a much lighter operational load for the club. Aanya gets a professional, repeatable format that makes future events easier to run and more attractive to students.
