GCSE Physics revision: a plan that works

By The STEM-Tutor team · Updated October 2026

GCSE Physics rewards understanding, practice with equations and clear written answers. Here is a plan to revise efficiently.

Start with the map

Use the full GCSE Physics topic list for your board and mark your strong and weak topics.

What to revise first

1. Equations: know every symbol and unit. See our GCSE Physics equations guide.
2. Electricity and forces: they carry a lot of marks.
3. Required practicals: method, variables and improvements. See our required practicals guide.

How to revise

• Answer questions rather than rereading notes.
• Mark your answers with official mark schemes and learn the key words.
• Keep a list of mistakes and redo those questions a week later.

Six-mark questions

Plan before writing. Use a logical sequence of points, include key scientific words, and link each point to the question.

A six-week plan

• Week 1: energy and electricity.
• Week 2: particle model and atomic structure.
• Week 3: forces.
• Week 4: waves, magnetism and electromagnetism, and space if you study separate Physics.
• Weeks 5 and 6: full past papers under timed conditions, then targeted review.

Worked six-mark answer

Six-mark questions are marked on how clearly and accurately you explain. Here is a model answer for a common question.

Example: terminal velocity

Describe and explain the motion of a skydiver from jumping out of a plane to reaching terminal velocity.

• When the skydiver first jumps, their speed is low, so air resistance is small. Weight is larger than air resistance, so there is a large resultant force downwards and they accelerate.
• As their speed increases, air resistance increases. The resultant force gets smaller, so the acceleration decreases.
• Eventually, air resistance equals weight. The resultant force is zero, so they stop accelerating and fall at a constant speed called terminal velocity.

Notice how each sentence links a cause to an effect, using words like “so” and “because”. That is what earns the top marks.

Worked calculation questions

Example: efficiency of a kettle

A 2000 W kettle takes 3 minutes to heat 1 kg of water from 20 °C to 100 °C. Find its efficiency. (c = 4200 J/kg °C)

• Useful energy = mcΔθ = 1 × 4200 × 80 = 336 000 J.
• Input energy = Pt = 2000 × 180 = 360 000 J.
• Efficiency = 336 000/360 000 ≈ 93%.

Example: stopping distance

A car travels at 15 m/s. The driver's reaction time is 0.8 s, and the braking distance is 18 m. Find the stopping distance.

• Thinking distance = speed × reaction time = 15 × 0.8 = 12 m.
• Stopping distance = 12 + 18 = 30 m.

Active revision methods

• Flashcards: definitions on one side, answers on the other. Test yourself, then shuffle.
• Blurting: write down everything you remember about a topic, then check your notes for gaps.
• Equation drills: practise rearranging and substituting until it is automatic.
• Past papers: sit them under timed conditions and mark them with the mark scheme.
• Teach it: explain a topic to someone else. If you can teach it, you understand it.

Using mark schemes

Mark schemes show the exact points examiners look for. After every past paper, compare your answer to the mark scheme and note the key words you missed. Over time you will see that the same ideas come up again and again, such as “resultant force is zero” or “energy is transferred to the thermal store of the surroundings”. Using these phrases in your own answers makes it easy for the examiner to give you marks.

Common mistakes

• Rereading notes instead of testing yourself.
• Leaving equations and units until the last week.
• Answering six-mark questions with a list of facts instead of linked explanations.
• Skipping the required practicals in revision.

Practice questions

Try each one before opening the answer.

Frequently asked questions

How early should I start revising GCSE Physics?

Steady revision from the start of Year 11 works well, with past papers from the spring. Earlier is better if you have gaps from Year 10.

What if I find the maths hard?

Practise the equations and rearranging little and often. Most physics maths uses a small set of skills that improve quickly with practice.

Key takeaways

• Use active methods: test yourself, do not just reread.
• Practise six-mark answers with linked explanations.
• Drill equations and units early.
• Sit past papers and learn from the mark scheme.
• Revise the required practicals as carefully as the theory.

A weekly revision routine

A simple routine works well for most students. On two days each week, revise one topic: read your notes, make flashcards, then do practice questions. On one day, do a set of mixed past paper questions and mark them. On another day, practise equations and units. At the weekend, review your flashcards and your mistake log. Short, regular sessions help you remember far more than long sessions the night before.

The mistake log

Keep a notebook for every question you get wrong. Write the question, what you did, the correct answer and the reason for the mistake. Was it a misread question, a wrong equation, a unit error, or a gap in understanding? Before each exam, read through your log. It is the most personal and useful revision resource you can have, because it targets exactly the mistakes you tend to make.

On the day

Read each question carefully, underlining key words such as “describe”, “explain” or “calculate”. Look at the marks for each question to judge how much to write. Show all working in calculations, because method marks can be earned even if the final answer is wrong. If a question seems hard, move on and come back. Use spare time at the end to check units and rounding.

Good preparation builds confidence, and confidence helps you think clearly in the exam.

Example: density

A metal cube has sides of 2 cm and a mass of 72 g. Find its density in g/cm³.

• Volume = 2 × 2 × 2 = 8 cm³.
• ρ = m/V = 72/8 = 9 g/cm³.

Balancing physics with your other subjects

GCSE students take many subjects, so plan your time across all of them. Use a weekly timetable with short physics sessions on several days rather than one long block. Pair physics with maths on some days, since the skills overlap, especially rearranging equations and reading graphs. Protect time for rest, exercise and sleep; a tired brain learns slowly. And celebrate progress, such as a better past paper score, to stay motivated through the revision period.

Remember that every past paper you complete, and every mistake you learn from, moves you closer to the grade you want.
