The International Mathematical Olympiad (IMO) is the world championship of high school mathematics. In Nepal, identifying and preparing the national delegation is a structured, merit-based process managed by the Mathematical Association of Nepal (MAN). This guide explains each tier of the competition pipeline, from local school participation to the international stage.
Overview of the Selection Pipeline
The selection pipeline follows three progressive competition tiers, followed by specialized national selection camps:
- District Mathematics Olympiad (DMO): Entry-level written examination conducted across all 77 districts of Nepal.
- Provincial Mathematics Olympiad (PMO): Regional proof-based examination across all 7 provinces for district qualifiers.
- National Mathematics Olympiad (NMO) and Team Selection: The premier national contest, which serves as the sole gateway to the Pre-TST, TST, and the final 6-member Nepal IMO delegation.
Stage 1: District Mathematics Olympiad (DMO)
The DMO is the primary entry point into Nepal's olympiad community. Held annually across all districts, this competition is open to secondary students in Grades 9 through 12. It casts a wide net, giving students throughout the country an opportunity to test their mathematical problem-solving ability beyond standard school curricula.
DMO Examination Format
- The DMO consists of a single written examination focusing on fundamental olympiad topics: elementary number theory, algebra, Euclidean geometry, and combinatorics.
- Top performers from each district earn qualification certificates and advance directly to the Provincial Mathematics Olympiad (PMO).
Students should prepare using the official topic syllabus and past question sets:
- 📘 Official Olympiad Syllabus: Detailed topic breakdown for all competition stages.
- 📂 DMO Past Papers (Google Drive): Real past contest papers from previous years.
Stage 2: Provincial Mathematics Olympiad (PMO)
Students who qualify through the DMO advance to the PMO. Organized across Nepal's seven provinces, the PMO raises the standard significantly. This stage transitions students from short-answer questions to full, proof-based problem solving.
PMO Examination Format
- The PMO is a comprehensive written test administered under strict proctoring at designated provincial centers.
- Problems require complete, rigorous proofs. Correct numerical answers without justified intermediate reasoning receive minimal marks.
- The highest-ranking students from each province qualify directly for the National Mathematics Olympiad (NMO).
Stage 3: National Mathematics Olympiad (NMO)
The NMO brings together the strongest qualifiers from all seven provinces. Organized centrally by the Mathematical Association of Nepal, this contest represents the highest domestic competition standard and serves as the benchmark for national honors.
National Selection: Pre-TST and Team Selection Tests (TST)
The Pre-TST and TST examinations take place exclusively after the NMO. They form the dedicated national selection process that identifies and prepares Nepal's IMO team.
Pre-TST (Preliminary Team Selection Test)
Administered to top NMO rank-holders, the Pre-TST serves as an evaluation filter. It tests depth across advanced olympiad topics and narrows the field to the most promising candidates for intensive national coaching.
TST (Team Selection Test)
The TST is the decisive final competition. Held over multiple days, it strictly mirrors the international IMO format: two competition days, each consisting of a 4.5-hour session with three problems worth 7 points each (maximum 42 points total).
Problems are drawn from shortlisted international proposals across geometry, number theory, functional equations, and combinatorics. The six students with the highest cumulative scores across all TST papers earn selection to the official Nepal National IMO Delegation.
Training Camp and the International Stage
Following selection, the six team members participate in a rigorous residential training camp led by MAN. Coached by university professors, experienced trainers, and past olympiad medalists, students work through international shortlists, refine solution techniques, and practice timed problem solving.
At the IMO, contestants compete individually over two days. Medals (Gold, Silver, Bronze) are awarded to approximately the top half of contestants, while an Honorable Mention is awarded to any participant who achieves a full score (7 out of 7) on at least one problem. Nepal achieved its first Honorable Mention in 2019 and secured its historic first Bronze Medal at the 66th IMO in Australia in 2025.
Advice for Aspiring Participants
- Master the fundamentals early: Students can begin preparing in Grade 8 or 9. Building a strong foundation in high school algebra and geometry makes advanced olympiad concepts far easier to assimilate.
- Prioritize proof writing: Practice writing complete arguments from start to finish. Clearly state any lemmas or theorems you use, and ensure every deduction is logically sound.
- Work with past papers: Solve past DMO, PMO, and NMO papers under timed conditions without consulting solution keys until you have made a genuine attempt.
- Balance all four subjects: Do not neglect geometry or combinatorics in favor of algebra alone. High placement requires competence across all four core areas.
The pathway from a local school classroom to the international IMO stage requires dedicated effort and genuine curiosity. Every problem you analyze strengthens your mathematical intuition. The Mathematical Association of Nepal continues to support students across the nation through accessible materials, training programs, and fair competition.
