GPL Challenge 2022

Our 2022 virtual Girls Programming League Challenge was held on Sunday, September 25, 2022. This year the theme of our contest was CS & Medicine!

The GPL Challenge is a one-day event comprising a programming contest, keynote speech, panel discussion, and awards, with the goal to inspire and empower young women to participate in computer science, technology, and AI. The competition will provide female students with the opportunity to solve creative programming problems in either a novice or advanced division, while the keynote speech and panel discussion aim to give the participants insight into the current state of the field from a female perspective.
