CSEC Physics exam format, paper structure, profile dimensions, syllabus sections, and study approach.
CSEC Physics assesses three profile dimensions across all papers:
| Profile | What it tests | Weighting |
|---|---|---|
| Knowledge and Comprehension (KC) | Recall, definitions, identification, basic concepts | 30% |
| Use of Knowledge (UK) | Application, calculation, explanation, prediction | 50% |
| Experimental Skills (XS) | Planning, measurement, analysis, interpretation | 20% |
Total marks: 200
The exam has three components.
| Component | Format | Duration | Marks | % of Total |
|---|---|---|---|---|
| Paper 01 | 60 multiple-choice items | 1 hr 15 min | 60 | 30% |
| Paper 02 | Structured and extended response | 2 hr 30 min | 100 | 50% |
| Paper 031 (SBA) | School-Based Assessment | School-assessed | 40 | 20% |
| Paper 032 (private candidates) | Practical examination | 2 hr 10 min | 40 | 20% |
Duration: 1 hour 15 minutes Questions: 60 items, each with four options (A-D)
Questions are drawn from all five syllabus sections. They test recognition, recall, simple calculation, and diagram interpretation. Paper 01 moves fast. If you genuinely do not know an answer, eliminate the two most obviously wrong options and move on.
Paper 01 rewards breadth. A student who has revised all five sections at a basic level will outscore one who knows two sections deeply and blanks on the rest.
Duration: 2 hours 30 minutes Structure: Section A (compulsory) + Section B (choice)
Three compulsory questions. The first question (worth 25 marks) is always a data analysis or graphical investigation. You are given experimental data and must plot a graph, calculate a gradient, and use it to determine a physical quantity. Past data-analysis questions have covered:
The remaining two compulsory questions are structured, covering topics from any syllabus section.
Three questions, of which you answer two. These are extended response questions requiring longer explanations, multi-step calculations, or combined reasoning. Topics rotate across the five sections, typically one question from electricity/magnetism, one from atomic physics, and one from mechanics or thermal physics.
In Paper 02, show all working even if you cannot reach a final numerical answer. Marks are awarded for correct method, correct substitution, and correct units separately. A wrong answer with a clear method still earns most of the marks.
The SBA assesses practical skills over the two-year course. A minimum of seven practical investigations must be completed, covering each section of the syllabus. The mandatory practicals are:
Four skills are assessed:
| Skill | What is expected |
|---|---|
| Planning and Designing (PD) | State aim, hypothesis, variables, method, expected results |
| Manipulation and Measurement (MM) | Use equipment correctly, take accurate readings |
| Observation, Recording, Reporting (ORR) | Record data in tables, draw diagrams, use correct format |
| Analysis and Interpretation (AI) | Calculate, identify patterns, draw conclusions, evaluate errors |
SBA marks are awarded on the quality of your write-up, not just whether your results are "correct". A well-documented experiment with a clear conclusion and identified limitations earns full marks even if your measured value differs from the accepted one.
Duration: 2 hours 10 minutes
This paper replaces the SBA for private candidates. It tests the same four skills through written questions that describe experimental situations. You may be asked to design an experiment, analyse given data, identify sources of error, or suggest improvements.
The syllabus is divided into five sections. Paper 02 questions draw from all five sections each year.
The foundation section. Topics build on each other, so a gap early on compounds.
Requires both kinetic theory reasoning and numerical calculation.
A mix of definition, diagram, and calculation.
The most calculation-heavy section. Also the one with the most applied/practical questions.
Requires understanding of nuclear notation, radioactive decay, and nuclear energy.
Paper 01 and the short-answer parts of Paper 02 test whether you know definitions, units, and facts precisely. "Resistance is opposition to current flow" is not specific enough. "Resistance is the ratio of potential difference across a conductor to the current flowing through it" is.
Most of Paper 02 tests whether you can use what you know to solve unfamiliar problems. This means substituting correctly into formulas, drawing correct ray diagrams, and applying principles such as conservation of momentum to collisions you have never seen before.
The data analysis question in Paper 02 tests whether you can extract information from a graph, calculate a gradient, and relate it to a physical quantity through an equation. Practice this skill explicitly, it is the highest-value single question on the paper.
Mechanics is the backbone. The concepts of force, energy, and momentum appear throughout other sections, including thermal physics (specific heat, gas laws) and electromagnetism (motor force, transformer power).
Ray diagrams, circuit diagrams, field line patterns, and force arrow diagrams appear every year. Practice drawing them accurately with a ruler and label every element.
The 25-mark graph question follows a predictable structure:
Practice this with past papers until it takes under 20 minutes.
The question patterns are consistent. The 2015-2024 May/June Paper 2 questions cover the same pool of topics with small variations. Use them to identify which topics appear annually (radioactivity, specific heat, lenses, transformers, momentum) and make sure you can answer those in your sleep.
