## What IGCSE Physics covers

The program teaches physics concepts across motion, energy, thermal physics, waves, electricity, magnetism, nuclear physics and space. It also develops experimental, data-handling and problem-solving skills.

Cambridge IGCSE Physics (syllabus 0625) is a two-tier qualification, aimed at students aged 14 to 16, that assesses physics knowledge, the handling of data and information, and experimental skills.

### Unit 1: Motion, forces and energy

Topics: Measurement Techniques and Scalar/Vector Quantities; Vector Addition and Resultants; Motion: Speed, Velocity, and Acceleration; Distance-Time and Speed-Time Graphs; Free Fall and Terminal Velocity; Mass, Weight, and Density; Effects of Forces: Elasticity and Hooke's Law; Newton's Laws and Circular Motion; Friction and Turning Effects (Moments); Centre of Gravity and Stability; Momentum and Impulse; Energy Stores and Transfers; Work, Power, and Efficiency; Energy Resources; Pressure.

### Unit 2: Thermal physics

Topics: Kinetic Particle Model and Brownian Motion; Gas Laws and Temperature Scales; Thermal Expansion and Heat Capacity; Melting, Boiling, and Evaporation; Conduction, Convection, and Radiation; Consequences of Thermal Transfer.

### Unit 3: Waves

Topics: General Properties of Waves; Light: Reflection and Refraction; Lenses and Dispersion; Electromagnetic Spectrum; Sound Waves.

### Unit 4: Electricity and magnetism

Topics: Magnetism and Magnetic Fields; Electric Charge and Current; EMF, Potential Difference, and Resistance; Circuit Components and Diagrams; Series and Parallel Circuits; Electromagnetic Induction and Generators; Magnetic Effect of Current and Motors; Transformers and Power Transmission.

### Unit 5: Nuclear physics

Topics: Atomic and Nuclear Models; Radioactivity and Decay; Half-life and Safety.

### Unit 6: Space physics

Topics: The Solar System and Universe.

## A class in IGCSE Physics, opened

Every class works like this. The tutor asks, you answer in your own words, and it reads what you wrote while you are still in the room, then tells you what is missing and asks you to try again.

A class, opened. A sample written to show how a class sounds (not a real learner); the scores show how the exam would credit each answer.

> **Motion · Distance-time graphs.** Question: What does the gradient of a distance-time graph tell you?
> The student wrote: The distance travelled. (the exam would credit 0 of 1)
> The tutor: The distance is read off the vertical axis. The gradient is the change in distance divided by the change in time. Which quantity has units of metres per second?
> The student then wrote: The speed of the object. (the exam would credit 1 of 1)

## How the IGCSE Physics exam is built

The assessment has three components. A 45-minute multiple-choice paper (Paper 1 for Core, Paper 2 for Extended) is 40 marks and 30% of the grade. A 1 hour 15 minute theory paper (Paper 3 for Core, Paper 4 for Extended) is 80 marks and 50%. Every candidate also takes one practical paper worth 20%: the hands-on Practical Test (Paper 5) or the written Alternative to Practical (Paper 6). Calculators may be used in all parts.

| Exam section | Detail |
| --- | --- |
| Paper 1: Multiple Choice (Core) | 40 questions · 45 min · 40 marks · 30% of the score; Calculator allowed |
| Paper 3: Theory (Core) | 75 min · 80 marks · 50% of the score; Calculator allowed |
| Paper 2: Multiple Choice (Extended) | 40 questions · 45 min · 40 marks · 30% of the score; Calculator allowed |
| Paper 4: Theory (Extended) | 75 min · 80 marks · 50% of the score; Calculator allowed |
| Paper 5: Practical Test | 75 min · 40 marks · 20% of the score; Calculator allowed |
| Paper 6: Alternative to Practical | 60 min · 40 marks · 20% of the score; Calculator allowed |

## How long does IGCSE Physics take?

Every level covers the whole syllabus. A deeper level only adds classes, so you can go deeper later and keep everything you have done. Hours are hours of teaching, counted in classes of 45 or 60 minutes.

| Level | Hours | Classes of 45 min |
| --- | --- | --- |
| Short | 3.8 | 5 |
| Standard | 18.2 | 25 |
| In depth | 27.5 | 37 |
| Extended | 35 | 47 |
| Full syllabus | 37 | 50 |

## Questions

**How many hours of teaching does IGCSE Physics take on Tutix?**

The Standard level takes 18.2 hours: 25 classes of 45 minutes, or 19 of 60. The Full syllabus level takes 37 hours (50 classes of 45 minutes). The Short level is 3.8 hours. Every level covers the whole syllabus; deeper levels add classes.

**What does the IGCSE Physics exam look like?**

As the board publishes it, the exam has these parts: Paper 1: Multiple Choice (Core) (40 questions, 45 minutes); Paper 3: Theory (Core) (75 minutes); Paper 2: Multiple Choice (Extended) (40 questions, 45 minutes); Paper 4: Theory (Extended) (75 minutes); Paper 5: Practical Test (75 minutes); Paper 6: Alternative to Practical (60 minutes). Check your board's current specification for the exact format of the year you sit it.

**Are there practice papers for IGCSE Physics?**

Yes. The Full syllabus level includes 2 full practice papers written for Tutix in the style of the real exam (52 questions and 160 marks each). You can sit them as long homework, and a class can go over them afterwards.

**Is this an official Cambridge IGCSE course?**

No. Tutix is not affiliated with Cambridge and its IGCSE Physics classes are not endorsed by Cambridge. The lessons and questions are Tutix's own, prepared to follow the published IGCSE Physics syllabus, and the real exam is set and marked by Cambridge.

**Can I try IGCSE Physics for free?**

Yes. The Free plan includes 45 live class minutes a month, about one class of the default length, and no card is needed. Pro is $15 a month for 360 live minutes (6 hours), and Pro+ is $30 a month for 900 live minutes.

**Is the IGCSE Physics tutor a person?**

No. The tutor is an AI. It talks with you in real time, teaches on a whiteboard, reads your answers and remembers what each earlier class covered. A parent can set up a child's classes and choose to get a recap after each one.

**Should I enter Core or Extended IGCSE Physics?**

Core candidates take the multiple-choice and theory papers on the Core content and can reach grades C to G. Extended candidates cover the Core content plus the Supplement and can reach A* to G. Your school decides the entry, so ask your teacher which tier you are being prepared for.

**When are the IGCSE Physics exams?**

Cambridge sets IGCSE exams in a June series and a November series, and offers a March series to centres in India. Schools enter their candidates; private candidates enter through an exam centre that accepts private candidates. Cambridge does not provide tuition to private candidates.

**Is IGCSE Physics the same standard as GCSE?**

Cambridge says it aligns IGCSE standards with the GCSE taken in England, and the syllabus cites a benchmarking study that found IGCSE comparable to the UK GCSE standard. Cambridge describes IGCSE as an international qualification for 14 to 16 year olds, though other ages can take it.
