• Key learning objectives for each topic

• Sample exam-style questions to support revision

Why Physics matters for GCSE success

GCSE Physics develops essential skills in calculation, logical thinking and data interpretation. Success in Physics often comes down to understanding and applying the core principles in unfamiliar contexts, a key requirement for high marks and future Science, Technology, Engineering, and Mathematics (STEM) study.

Whether students go on to study engineering, medicine, environmental science or technology, a good understanding of Physics helps them take the next step in their education and builds useful skills like problem-solving, critical thinking and working with numbers.

Exam boards and specification overview

GCSE Physics is studied in two formats:

• As part of Combined Science (2 GCSEs across Biology, Chemistry and Physics)

• As a separate GCSE (Triple Science), giving students one full GCSE in Physics Combined Science vs Triple Science

Combined Science vs Triple Science

Triple Science students often study more advanced applications, such as momentum, space physics or thermal conductivity calculations.

This gives them more opportunities to score highly, but also requires deeper understanding and problem-solving skills.

Exam board overview

While the themes are consistent, each exam board organises the content slightly differently:

*OCR offers more than one pathway (e.g. Physics A: Gateway Science and Physics B: Twenty-First Century Science). The core content is very similar, but topics may be grouped differently and assessed in slightly different ways. Make sure to check with your teacher which pathway your school is using.

Tips for revision and exam preparation

A strong revision plan for GCSE Physics combines understanding key principles with regular, targeted practice. Here are some strategies that help students engage meaningfully with the subject and build exam confidence:

1. Break topics into manageable chunks

Physics spans a wide range of concepts, from forces and energy to electricity and waves. Divide revision into focused topics such as motion, magnetism or radiation, so students can concentrate on one idea at a time.

This approach helps prevent overwhelm and builds a stronger foundation across the specification.

2. Use active recall and self-testing

Effective Physics revision goes beyond re-reading notes. Use techniques like flashcards for key equations, definitions and units, or try explaining concepts aloud without notes. Regular self-testing strengthens memory recall and helps identify weak spots early.

3. Apply concepts through exam-style questions

Physics questions often present familiar concepts in unfamiliar contexts. Practising with exam-style questions throughout revision (not just at the end) helps students apply their knowledge, improve problem-solving skills and understand how marks are awarded.

4. Practise interpreting data and graphs

Data analysis is a key skill in GCSE Physics. Students should practise reading graphs, calculating gradients, and drawing conclusions from experimental data. These skills are especially important for required practicals and extended-response questions.

5. Start with the challenging topics

Areas such as forces in motion, energy transfers, or electromagnetism can be more demanding. Address these earlier in the revision process to allow time for repeated practice and clarification. Leaving these until later can create unnecessary pressure.

6. Use visual representations

Diagrams, circuit symbols, ray diagrams and motion graphs are central to Physics understanding. Encourage students to draw and label diagrams from memory, or to create flow charts that link processes (e.g. energy transfers in a system). Visual tools help clarify abstract ideas and improve retention.

7. Get comfortable with equations and units

Students need to know which formulas to memorise and how to rearrange them confidently. Practice should include identifying correct units, converting values, and checking final answers for accuracy. Building fluency with equations reduces anxiety and improves performance in calculation-heavy questions.

Final thoughts

With the right strategy and tools, GCSE Physics doesn’t need to be stressful. Focus on consistent revision, practise past questions, and remember small steps lead to big gains.
