Where Kangaroo is one multiple-choice paper per age, UKMT is a progression. The Challenge and its Kangaroo follow-on are multiple choice — but the Olympiad rounds ask for full written solutions, marked on reasoning, not just the answer. That last step is why UKMT gets its own space.
Junior, Intermediate and Senior — 25 multiple-choice questions against the clock. The entry paper everyone sits.
The follow-on round for strong Challenge scores. Still multiple choice, but a sharper, faster set of problems.
JMO, the Cayley–Hamilton–Maclaurin papers, then BMO. Full written proofs — a different discipline, and a different practice mode.
The multiple-choice levels will run on the same engine as IKMC, retuned for UKMT’s timing and marking. The Olympiad proof practice is a separate build — you can’t auto-mark a proof the way you score a multiple-choice answer, so it’ll be its own mode rather than a level of the test engine.
