II. Four-Stage Roadmap for Zero-Base Preparation

The following roadmap assumes you are starting from zero with a preparation time of about 6-9 months (e.g., starting preparation in September for the exam in April of the following year).

Stage	Time Suggestion	Core Goal	Specific Actions & Learning Content	Resources & Tools
Stage 1: Foundation Building & Interest Stimulation	6-9 months before exam	Consolidate basic school math, cultivate interest in math and logical thinking habits.	1. Solid Mastery: Ensure complete mastery of school math (especially arithmetic, basic geometry, fractions, decimals, percentages). 2. Fun Expansion: Engage with logic puzzles, Sudoku, visual reasoning, simple math competition introductory problems to cultivate interest. 3. Initial Familiarization: Browse 1-2 sets of JMC past papers from 3-5 years ago to get a feel for the question types and difficulty. Do not time yourself, just experience it.	School math textbooks, fun math reading materials, logic puzzle books, past papers from the UKMT official website (start with the oldest ones).
Stage 2: Systematic Learning & Question Type Mastery	3-6 months before exam	Systematically learn core JMC knowledge points and train by topic.	1. Modular Learning of Knowledge Points: Conduct thematic study based on high-frequency JMC topics (see the knowledge points table below). 2. Practice by Question Type: Categorize past papers by question type (e.g., number theory, geometry, combinatorics) for practice, summarizing common solution methods and thinking patterns for each type. 3. Create a Mistakes Log: Record mistakes and difficult questions, analyze the reasons (unclear concept, wrong approach, or carelessness), and review regularly.	Past papers (categorized by module), basic math competition tutorials (focusing on fun and thinking, not advanced knowledge), a mistakes log.
Stage 3: Comprehensive Simulation & Speed Improvement	1-3 months before exam	Conduct full-length mock exams to adapt to the exam rhythm and improve solving speed and accuracy.	1. Timed Mocks: Complete 1-2 recent past papers weekly, strictly timing yourself for 60 minutes to simulate the real exam environment. 2. In-depth Review: After the mock, not only check the answers but spend double the time analyzing: - For correct answers: Is your approach optimal? - For wrong answers: Where did you get stuck? What is the correct approach? - For unanswered questions: Is it a time management issue or a weak knowledge area? 3. Strategy Optimization: Develop your own test-taking strategy, such as tackling easier questions first, managing time wisely, and using multiple-choice techniques (substitution, elimination, estimation, etc.).	JMC past papers from the last 5-8 years, a timer, an answer sheet.
Stage 4: Final Sprint & Mental Preparation	1 month before exam	Fill in knowledge gaps, maintain practice rhythm, and adjust to optimal test-taking state.	1. Return to Mistakes: Focus on reviewing all questions in your mistakes log to ensure similar errors are not repeated. 2. Maintain Practice Rhythm: Complete 1 simulation test or redo a past paper weekly to keep your mind active, but stop pursuing very difficult or unusual questions. 3. Mental Preparation: Understand the exam process, ensure adequate rest, and approach the test with a calm mindset. Set a clear goal: achieve the highest possible score within the limited time, rather than completing all questions.	Mistakes log, 1-2 unseen simulation tests or past papers.
