Note that for the contests hosted on kattis, you can't submit problems on the (long-completed) contest's page; instead you can submit problems at open.kattis.com/problems/problemName.

You can also practice with the problems from previous year's North American Qualifier for 2023. 2022, 2020, 2019, 2018, 2017, 2016, etc.

Judging solutions and data are (intentionally) non-public, but we are happy to share them with coaches; we just ask that you not publish/release it. Coaches should email ibarland@radford.edu to be added to the google-group "mid-atlantic-icpc-judges-and-coaches", or for old problem set .zip's directly. (Providing a link to a faculty-page, or other evidence of coachhood, is appreciated.)
