The 2026-27 SMC exam is officially scheduled — the UKMT official competition calendar confirms that the Senior Mathematical Challenge will be held on Wednesday, 7 October 2026, with registration opening on the same day. The 2025-26 SMC was completed on 10 October 2025, with results and certificates already published. According to UKMT official information, SMC is open to students in Year 12 (Grade 12) and below, and is a flagship high school mathematics competition with over 100,000 participants worldwide each year. Gold award winners are invited to participate in the subsequent BMO Round 1. Currently in August 2026, with about 2 months until the exam on 7 October 2026, this is the most critical sprint window for "systematic summer practice + timed mock exams".
A key clarification is needed: SMC is a personal written test with 90 minutes, 25 questions, and a total score of 125. The scoring rule is "starting score of 25, +4 for correct answers, -1 for wrong answers, 0 for unanswered" — this means blind guessing will severely lower the total score, and "skipping uncertain questions" is a hard rule. Its core difficulty is the dual challenge of "speed + accuracy": 90 minutes for 25 questions, averaging only 3.6 minutes per question. The first 15 questions are basic, while the last 10 are advanced. The China region is organised by ASDAN; individuals cannot register directly and must register through their school or an authorised agency. The following is a four-layer breakdown: "Competition format + 90-minute time allocation + Summer to October sprint cycle + Preparation calendar".
Core understanding of the competition format: "The difficulty of SMC is not in the individual question difficulty, but in the '-1 point for wrong answers' mechanism, which requires both daring to attempt and avoiding blind guessing; within 90 minutes, the average is 3.6 minutes per question, with the first 15 questions being the 'safe zone' of basic questions and the last 10 being the 'risk zone'". UKMT officially states that SMC is for Year 12 and below students, with bilingual English-Chinese papers. The 2025 China region exam was held on 10 October 2025 from 17:00 to 18:30, with a full score of 125. The 2025 award cutoffs were: Gold 72+, Silver 57+, Bronze 46+; a score of 104 or above qualifies for BMO Round 1. This means preparation must focus on three parallel tracks: "accuracy on basic questions + selective tackling of advanced questions + timed mock exams", and the discipline of "skipping" must be trained.

Core understanding of the competition format: "The 2025-26 SMC has concluded (exam on 10 October 2025, results and certificates already published). The 2026-27 SMC exam is officially scheduled by UKMT for Wednesday, 7 October 2026, with registration opening the same day." The UKMT Competition Calendar 2026-27 and the homepage both list the Senior Mathematical Challenge for Wednesday 7th October 2026. The 2025 China region exam was on 10 October 2025 from 17:00 to 18:30, with a full score of 125, Gold 72+, Silver 57+, Bronze 46+, and 104+ qualifying for BMO Round 1. The China region is organised by ASDAN; individuals cannot register directly and must register through their school or an authorised agency; registration is expected to open in September 2026. Currently in August 2026, with about 2 months until the exam on 7 October 2026, this is the most critical sprint window for "systematic summer practice + timed mock exams".
2. How to Allocate 90 Minutes for 25 Questions
- First Round: Quick Harvest (Q1-10, ≤25 minutes): Build confidence and advance steadily; among the first 10 questions, there are several "easy points" that must be secured; if stuck (thinking over 1.5 minutes), mark and skip immediately.
- Second Round: Steady Attack (Q11-20, ≤35 minutes): Core differentiating questions, the watershed for Gold and Silver awards; allocate 3-5 minutes for deep thinking per question; only answer if the approach is relatively clear; under the "-1 point for wrong answers" mechanism, resolutely skip uncertain questions.
- Third Round: Challenge and Review (Q21-25 + review, ≥30 minutes): The last 5 questions are key to high scores, requiring sufficient deep thinking time; leave 5 minutes to check the answer sheet and marked questions; 0 points for unanswered is better than blind guessing.
- Skipping Discipline: The "-1 point for wrong answers" applies throughout SMC, making blind guessing extremely costly; must establish the discipline to "skip if uncertain" and allocate time to questions with a clear approach.
- Target Correct Answers: To aim for Gold, need 18+ correct answers (approx. 77 points + starting 25 = 102 points); 104+ qualifies for BMO Round 1.
The essence of the 90-minute allocation: "Q1-10 ≤25 minutes + Q11-20 ≤35 minutes + Q21-25 and review ≥30 minutes — the three-round time allocation method, with the core being 'front tight, back loose, skip discipline'". UKMT officially states the scoring rules as starting score 25, +4 for correct, -1 for wrong, 0 for unanswered, full score 125 — meaning blind guessing will severely lower the total score. The "-1 point for wrong answers" applies throughout, making blind guessing extremely costly; the discipline of "skip if uncertain" must be established. The first 10 questions are the concentration zone for "easy points" and must be secured; Q11-20 are the watershed for Gold and Silver awards, requiring deep thinking; Q21-25 are key to high scores, requiring 30 minutes. Starting the sprint in August 2026, within 2 months, the three-round time allocation method must be trained into muscle memory — timed mock exams are the only test standard.
II. How to Sprint from Summer to the October Exam
1. Summer Foundation Building Period (August 2026)
- August 2026 (Systematic review of knowledge modules): Systematically go through the four major modules: Geometry & Space (~30%), Number Theory & Algebra, Combinatorics, and Logical Reasoning; 8-10 hours per week; carefully work through past papers from 2018-2025 by topic.
- Core Task: Build pattern recognition skills for question types; focus on breaking through the Geometry & Space module (~30%) — power of a point theorem, properties of triangle centres, coordinate transformation in analytic geometry, cross-sections and volumes of solids of revolution in 3D geometry.
- August Goal: Complete the knowledge framework for all four modules; acquire the basic ability for timed mock exams.
Core of the summer foundation period: "August is the golden window for systematic review of the four modules, with Geometry & Space (~30%) being the top priority". SMC knowledge modules cover Geometry & Space (~30%), Number Theory & Algebra, Combinatorics, and Logical Reasoning; no advanced mathematics but emphasises flexible application. Geometry & Space has the highest proportion, including power of a point theorem, properties of triangle centres, coordinate transformation in analytic geometry, and cross-sections and volumes of solids of revolution in 3D geometry — these are the hard nuts that must be cracked during the summer. Starting in August 2026, with only 2 months until the exam on 7 October 2026, August must be used to complete the systematic review of knowledge modules and initial topic-based practice of past papers; otherwise, the timed mock exams in September cannot proceed.
2. Timed Mock Exam Sprint Period (September 2026 – 7 October 2026)
- September 2026 (Registration + Timed Mock Exams): Registration for the China region is expected to open in September; complete registration through school or ASDAN authorised agency; 2-3 full-length 90-minute timed mock exams per week; strictly train the three-round time allocation method.
- Early October 2026 (One week before the exam): Stop learning new knowledge; do 1 timed mock exam per day to maintain form; adjust sleep schedule to ensure peak energy during the exam period; official exam on Wednesday, 7 October 2026.
- Key Dates: Referring to the 2025 China region schedule, registration usually closes 1-2 weeks before the exam (2 October 2025 for 2025); UKMT official schedule for 7 October 2026, China region specific timing subject to ASDAN announcement.
- Mock Exam Discipline: 90 minutes, 25 questions, calculators prohibited; train the "skip and mark" method; target 18+ correct answers for Gold, 104+ for BMO Round 1.
Core of the timed mock exam period: "Registration in September + 2-3 timed mock exams per week, stop new knowledge before 7 October and do 1 mock exam per day to maintain form — the 2-month sprint period determines the award level". Registration for the China region is expected to open in September 2026; referring to the 2025 schedule, registration closes 1-2 weeks before the exam (2 October 2025). UKMT officially confirms 7 October 2026 (Wednesday) as the SMC exam date. September must enter the rhythm of 2-3 full-length 90-minute timed mock exams per week, strictly training the three-round time allocation method of "Q1-10 ≤25 minutes + Q11-20 ≤35 minutes + Q21-25 and review ≥30 minutes". Under the "-1 point for wrong answers" mechanism, blind guessing is extremely costly — the core of mock exams is not how many questions you get right, but training the discipline to "skip if uncertain". One week before the exam, stop learning new knowledge and do 1 timed mock exam per day to maintain form.
III. 2026 Second Half SMC Preparation Calendar
1. Summer Systematic Review Period (August 2026, approx. 1 month)
