Aadi Arya Karthik’s final quiz bowl tournament turned out to be the 2025 ACF Regionals @ Imperial
College on February 01, 2025 helping Oxford A defeat Cambridge A, helping Oxford qualify for ACF nationals in the US. Final score Oxford A 420, Cambridge A 140. Technically, third national championship that he and his different teams of 3 others have been part of, though the last one was UK.
Individually, Aadi Arya Karthik top scored.

On February 1, 2025, several transit issues affected travel across the UK causing angst for one of the members of Oxford A team. The team was mentioning how fast Aadi Arya played that day to get the tournament finished so the distressed Oxford A player can get on an earlier train and avoid the disruption. The appreciation from those team members for the compassionate actions of Aadi Arya while also making sure Oxford won was gratifying to hear and the behavior we had come to expect.
