The Siam International Math and Science Olympics (SIMSO) is a prestigious competition based in Thailand that challenges students from Kindergarten to Grade 12 in logical reasoning and scientific inquiry. Practicing with past papers is the most effective way to understand the exam's unique structure and difficulty level. Exam Structure and Format

Before diving into the papers, it is crucial to know what you are preparing for. SIMSO is highly differentiated by grade level: Lower Primary: Specifically designed for Sr. Kg to Grade 2. Middle/Upper Primary: Covers Grades 3 to 6. Secondary: Covers Grades 7 to 10. Senior Secondary:
1. What is SIMSO?
| Feature | Description |
|---------|-------------|
| Purpose | A lightweight, open‑source Python‑based simulator used to model and evaluate real‑time scheduling algorithms on uniprocessor and multiprocessor platforms. |
| Key Modules | simso.core (event engine), simso.scheduler (algorithm implementations), simso.visualizer (Gantt charts, statistics). |
| Typical Use‑Cases | • Academic labs for Operating‑Systems / Real‑Time Systems courses. • Research prototyping of novel scheduling policies. • Benchmarking of task sets (periodic, aperiodic, sporadic). |
| Supported Algorithms | Fixed‑Priority (Rate‑Monotonic, Deadline‑Monotonic), EDF, PFair, LLF, Global/Partitioned variants, custom user‑defined policies. |
| Input/Output | • XML task‑set description (period, WCET, deadline, offset). • JSON configuration for platform (CPU count, speed‑scaling). • CSV/HTML reports, Gantt visualisations. |
