Five stages, real problem sets, and scoring designed to match the standard of IOI, PAIO, and AOAI, so students arrive prepared, not surprised.
Each problem is scored across a set of hidden test cases covering edge cases, performance limits, and correctness; full marks require a fully correct, efficient solution, but partial solutions earn partial credit.
C++, Python, and Java are supported across every round, with identical time and memory limits per language so no language choice is disadvantaged.
Tanzania's strongest performers are prepared to represent the country at the following competitions.
Competition results are published after each contest and include national rankings, regional rankings, medal winners, certificates, and national team selection.
