IGCSE Physics exam technique 2026: The complete guide to scoring higher in 0625

IGCSE Physics exam technique is about turning subject knowledge into accurate, well-structured answers that match what Cambridge examiners are looking for. Students need to interpret command words correctly, manage their time across different papers, show clear working in calculations, use the correct units and significant figures, and handle graph and data questions carefully. Strong technique also helps students secure method marks and avoid losing easy marks through incomplete or poorly presented answers.

This guide explains the key strategies students can use across Cambridge IGCSE Physics 0625 to improve consistency and maximise their exam performance.

How to read and interpret IGCSE Physics questions correctly

Before you write a single word, you need to understand exactly what the question is asking. Cambridge examiners are precise. Every word in a question stem carries marking weight, and misreading the command word is one of the fastest ways to lose marks.

The most critical skill in the Cambridge 0625 ^[1] strategy is recognizing command words and responding to them correctly. The table below outlines the most common command words in IGCSE Physics and what each one requires from you.

One critical detail often overlooked is the difference between “describe” and “explain.” Students routinely write an explanation when the question only asks them to describe a phenomenon, and vice versa. Both earn zero marks if the wrong type of response is given. Read the command word first, underline it, and then plan your answer accordingly.

Hidden numerical values are another reading trap. Cambridge routinely embeds key data inside the question text rather than presenting it as a clean list. The phrase “starts from rest” means initial velocity u = 0 m/s. “Moving at constant velocity” means acceleration a = 0 and resultant force = 0. “An echo is heard” means the sound wave has traveled twice the stated distance. Training yourself to extract these hidden values before writing anything is a foundational IGCSE Physics tip that separates strong candidates from average ones.

Time management strategies for IGCSE Physics Paper 2, Paper 4 and Paper 6

Poor time management is one of the leading causes of avoidable mark loss in 0625. Each paper has a distinct rhythm, and your pacing strategy must match that rhythm.

For Paper 2, the multiple choice strategy is straightforward: Do not spend more than 90 seconds on any single question. If you are unsure, mark it, move on, and return at the end. There is no penalty for a wrong answer in Cambridge MCQ papers, so every question must have a response. A blank answer is always wrong; a considered guess has a 25% chance of being correct.

For Paper 4, the most effective time management technique in IGCSE Physics 0625 is to read the entire paper in the first three minutes. This allows you to identify which questions you can answer quickly and which will require more thought. Tackle your strongest topics first to build confidence and secure marks early.

For Paper 6, the 7-mark planning question at the end of the paper is a significant time investment. Allocate at least 12 to 15 minutes for it. Students who rush this question and write vague answers consistently lose 4 or more marks, which can shift an entire grade boundary.

A rule used consistently across Times Edu‘s IGCSE Physics coaching is the “two-minute warning” rule: If you have been on a single part of a question for two minutes and are still stuck, move on. Partial credit from the next question is always more valuable than zero credit from a question you cannot solve.

How to show working and include units in IGCSE Physics calculations

Calculation technique in IGCSE Physics is arguably the most mark-generative skill on Paper 4. Cambridge’s mark scheme awards method marks independently of the final answer, which means a student who sets up the working correctly but makes an arithmetic error can still earn 2 out of 3 marks.

At Times Edu, we teach a structured five-step method called FISUE for every calculation question. This approach ensures you never lose an easy mark through carelessness.

F: Formula. Write the formula in its original form before doing anything else. For example: P = W/t, or v = f x lambda. This earns an immediate method mark.

I: Insert. Place the numerical values from the question directly into the formula. Do not rearrange first. Inserting values first gives the examiner clear evidence that you understand which quantity is which.

S: Substitute or rearrange. If the target variable is not already isolated, rearrange the equation at this step. Cambridge markers follow your working line by line, so each step must be visible.

U: Unit. State the unit explicitly alongside your final answer. Missing a unit in IGCSE Physics is an automatic one-mark deduction. Common units to memorize include Joules (J), Watts (W), Pascals (Pa), Newtons (N), and Ohms (Omega).

E: Evaluate. Ask yourself whether the answer is physically reasonable. If you calculate that a walking person is moving at 300 m/s, a decimal error has occurred somewhere. This self-check step takes five seconds and can save two marks.

Significant figures in IGCSE Physics are another source of needless mark loss. The standard Cambridge rule is to give your answer to the same number of significant figures as the data provided in the question, typically two or three. Writing an answer to seven decimal places does not earn extra credit and can actually trigger a significant figures penalty.

Exam technique for describe and explain questions in IGCSE Physics

Multi-mark descriptive questions, typically worth 3, 4, or 5 marks, follow a highly predictable mark scheme structure. Cambridge examiners award one mark per distinct physical point. This means your answer must contain as many clear, separate scientific statements as there are marks available.

The most effective format for these questions is a bullet-point list. Each bullet should contain one physical cause, one observable effect, or one logical link between them. Do not merge two ideas into a single sentence, as Cambridge markers often credit only one idea per bullet.

Drawing on years of experience at Times Edu reviewing student scripts, the most commonly penalized response is one that restates the question in different words. For example, when asked to explain why pressure increases as depth increases in a liquid, writing “pressure increases because there is more pressure at greater depth” earns zero marks. The correct response introduces a new physical concept: The weight of the liquid column above the point increases with depth, increasing the force per unit area acting on that point.

The “state and explain” question type is a specific variant that catches many students off guard. The “state” part earns one mark for a direct factual claim. The “explain” part earns the remaining marks for the scientific reasoning behind that claim. If you write only the explanation and omit the initial statement, the mark scheme may withhold the first mark.

For extended explanations of processes such as convection, radioactive decay, or terminal velocity, follow this internal structure for each step: Identify the physical quantity that changes, state the direction of change, and give the physical reason for that change. This three-part logic for each step guarantees that your answer aligns with how Cambridge’s mark scheme is written.

How to approach data response and graph questions in IGCSE Physics

Data response questions in IGCSE Physics appear across Paper 4 and Paper 6. They test your ability to extract, interpret, and analyze information presented as tables, graphs, or diagrams. This is a skill set that requires its own deliberate practice.

When reading a graph, always identify the axes, units, and scale before attempting to extract a value. A common error is misreading the scale on the y-axis when it does not start at zero or uses an unfamiliar increment.

Plotting graphs on Paper 6:

• Use a sharp pencil throughout. Ink or a blunt pencil produces thick marks that obscure the exact position of the point.
• Mark data points with a small, precise cross (x) or a dot enclosed in a circle. Large blobs indicate imprecise technique and lose marks.
• Draw a line of best fit in a single, continuous stroke. The line must have roughly equal numbers of data points above and below it. It does not need to pass through any specific point, including the origin.
• Anomalous points should be clearly identified and excluded from the line of best fit. Circle the anomalous point and label it as anomalous to demonstrate awareness.

Finding the gradient: This is one of the most frequently tested skills in the Cambridge Physics exam approach. Draw a large right-angled triangle on the line of best fit. The hypotenuse of the triangle must span at least half the total length of the drawn line. Read the coordinates of the two triangle vertices directly from the graph, not from your original data table. Divide the vertical change by the horizontal change, and include the correct unit for the gradient.

One mistake we see consistently in Paper 6 scripts is a gradient triangle that is too small, covering only two or three data points near one end of the graph. A small triangle amplifies the effect of any reading error and reduces the precision of the gradient. Cambridge specifically checks triangle size and deducts marks for inadequate technique.
