The 2026 IPC and SPC Online competitions have successfully concluded. As the “golden ticket” to BPhO participation eligibility in China, this year's events continued the style of emphasizing fundamentals, application, and modeling. However, candidate performance was clearly polarized: those with solid foundations scored easily, while those who overlooked details frequently lost points.
This article provides a comprehensive review across four dimensions: exam structure, score cut-off predictions, module breakdown, and preparation insights, offering precise strategies for 2027 preparation.

2026 Award Score Cut-off Predictions (Based on Candidate Feedback and Historical Data)
CompetitionGoldSilverBronzeIPC29–33 points21–28 points≥12 pointsSPC27–31 points19–26 points≥10 points
Key Trends:
The SPC Gold cut-off is approaching a perfect score (31/30), reflecting intense competition at the high-score level.
The IPC Bronze threshold is low, but achieving Silver or Gold still requires systematic training.
II. In-depth Breakdown of the Five Modules: Where Are the Score-Boosting Opportunities and Key Differentiators?
1. Kinematics & Mechanics (35%) — The Core of the Core
IPC: Direct application of formulas.
SPC: Requires modeling before solving. For example:
- “Change in potential energy when a person walks on a treadmill” → Abstract into center of mass height change + energy conservation.
- “Spring compression after collision” → Combine conservation of momentum + conservation of mechanical energy.
Strategy: Ensure zero errors on foundational questions. Top students should focus on multi-process comprehensive problems.
2. Thermal Physics & Energy (25%) — Most Life-Connected, Highest Error-Prone
Typical Scenarios:
Sand battery energy storage (specific heat capacity calculation).
Antarctic airlock thermal equilibrium (heat conduction + energy conservation).
High-frequency Points of Deduction:
Units not unified (e.g., mixing kJ and J).
Incorrect significant figures (e.g., problem gives 2 digits, answer writes 5).
Ignoring latent heat of phase change (e.g., ice → water requires heat absorption).
Strategy: Develop the habit of “convert units first, then set up equations, finally check dimensions.”
3. Electromagnetism (15%) — Foundation Score Area, No Room for Error
Key Topics:
Series and parallel circuit calculations.
Thermistor characteristics.
Ideal meters (ammeter internal resistance ≈ 0, voltmeter internal resistance → ∞).
Common Mistakes:
Misjudging circuit structure (viewing mixed connections as purely series/parallel).
Ignoring the effect of meters on the circuit.
Strategy: This module has a high scoring rate; aim for full marks.
4. Atomic Physics & Astronomy Applications (10%) — Easy Points, Don‘t Lose Them Carelessly
Atomic Physics: Half-life calculations, types of radiation.
Astronomy Applications: Kepler‘s Third Law.
Characteristics: The problem provides formulas or context; only substitution and calculation are required.
Strategy: Memorize 5 core formulas + 3 radiation types before the exam to quickly secure points.
5. Experimental Measurement & Model Derivation (15%) — The Key to Differentiating Performance
IPC: Explaining classical experiments (e.g., principle of mercury barometer, sources of error in friction measurement).
SPC: Building physical models.
Strategy: Train the thinking chain of “phenomenon → principle → formula,” avoiding rote memorization of conclusions.
III. Four Core Preparation Takeaways: How to Sprint Efficiently in 2027?
1. Grasp the Fundamentals: 80% of Points Come from Core Modules
Mechanics, thermal physics, and electromagnetism account for over 75% of the total. Prioritize ensuring zero errors in these sections. Create a “high-frequency formula list” and review it daily.
2. Control the Details: Units, Significant Figures, Ideal Models
First step in all calculation problems: unify units (e.g., m → km, g → kg).
Retain significant figures consistent with the problem statement.
Keep “idealized assumptions” in mind (e.g., smooth = no friction, light string = mass negligible).
3. Build Models: Extract Physical Essence from Life Scenarios
Train using the “keyword positioning method”:
“Turn” → circular motion
“Slowly heated” → quasi-static process
“Floating in the air” → buoyancy = gravity
Analyze one long-answer question from past exams each week to practice modeling steps.
4. Practice Calculations: Improve Both Speed and Accuracy
Timed practice: 60 minutes for IPC / 90 minutes for SPC.
Use a scratch paper zoning method: dedicate a separate area for each problem to avoid confusion.
Maintain an error log to record “types of calculation errors” (e.g., sign errors, exponent miscalculations).
