Q: What does Singapore Physics Olympiad (SPhO): Parent & Student Guide cover?\ A: Evergreen reference to SPhO structure, scoring, timeline and prep strategy for IP and JC candidates.
TL;DR\ SPhO rewards deep conceptual fluency in mechanics, E&M, and thermal/modern topics, plus disciplined practical skills.\ Use this as an orientation, but always follow the latest official IPS/SPhO circular for dates, format, and eligibility for your cohort.
Registration quick answer (Singapore): Schools nominate candidates to SPhO; individual sign‑up is not offered. Yearly circulars and dates are announced via official organisers — check NUS Physics’ SPhO page for current instructions: https://www.physics.nus.edu.sg/olympiad/spho
1 What is SPhO?
- Organiser: Institute of Physics, Singapore (IPS)
- Format: 4-h Theory + 4-h Practical (on separate days)
- Typical cadence: November sittings; awards/ceremony thereafter
- Eligibility: JC/IP candidates via school nomination (confirm yearly details)
2 Why SPhO matters for IP students
- Curriculum bridge: accelerates H2 mastery; primes H3 research modules
- Portfolio signalling: nationally recognised achievement; pipeline to APhO/IPhO
- Metacognition: planning experiments under time pressure mirrors A-Level Paper 3/4 skills
3 Paper structure and scoring
- Theory: long structured problems; vector fluency, calculus in context
- Practical: measurement, uncertainty propagation, calibration, graphing
- Marking emphasis: physical reasoning, clear assumptions, units & sig-fig discipline
Theory question patterns (illustrative)
- Multi-stage mechanics: modelling with free-body diagrams → differential equation → limiting behaviour.
- Circuits with non-idealities: internal resistance, non-ohmic elements, measurement loading.
- Fields and induction: flux reasoning, Faraday/Lenz in time-varying scenarios, energy transfer routes.
- Thermal/modern: ideal-gas modelling limits, kinetic-theory estimates, simple decay chains.
4 Core topics and prep priorities
- Mechanics: dynamics, energy, oscillations; multi-step modeling
- E&M: fields, circuits, induction; idealisations vs real components
- Thermal/Modern: kinetic theory, thermodynamic cycles, basic atomic/nuclear models
- Mathematical methods: series approximations, dimensional analysis
