The first CCAMB was held in 2006. We unfortunately no longer have the problems and results from early years of CCAMB.
CCAMB 2025 was the first year with two separate divisions. The difficulties of the rounds in previous years roughly correspond to that of the current Division I.
Problems and discussion can also be found at our AoPS archive.
