A level Physics revision: a plan that works

By The STEM-Tutor team · Updated October 2026

A level Physics rewards understanding and practice. Here is how to revise efficiently in the months before your exams.

Know the content map

Start with the full A level Physics topic list for your board and rate each topic red, amber or green.

Revise actively

1. Definitions: learn them word for word. Many marks depend on exact wording.
2. Equations: know what each symbol means, using your board's formula sheet.
3. Questions: spend most of your time answering exam questions, not reading notes.
4. Mark schemes: mark your own work and copy the key phrases examiners look for.

Practical skills

Every board tests practical skills in the written papers: methods, uncertainties and graph analysis. Revise your required practicals regularly.

Multi-step and synoptic questions

Top grades depend on longer questions that combine topics. Practise breaking them into steps, writing each equation you use, and checking units at the end.

A twelve-week plan

• Weeks 1 to 4: red topics first, with topic-based questions.
• Weeks 5 to 8: amber topics and practical skills.
• Weeks 9 to 12: full past papers under timed conditions, followed by targeted review.

Maths for physics

Keep logarithms, rearranging and graph skills sharp. Many marks are lost on maths, not physics.

A worked synoptic question

Synoptic questions combine ideas from different topics. Here is one that links mechanics, energy and electricity, the kind of chain that appears in the longer questions.

Example: a small electric motor

A motor lifts a 0.50 kg mass through 1.2 m in 4.0 s. It runs from a 6.0 V supply and draws 0.40 A. Find its efficiency.

• Useful energy output = mgh = 0.50 × 9.81 × 1.2 ≈ 5.9 J.
• Electrical energy input = VIt = 6.0 × 0.40 × 4.0 = 9.6 J.
• Efficiency = 5.9/9.6 ≈ 61%. The rest is dissipated as heat and sound in the motor.

Example: a charged particle in a field

An electron is accelerated from rest through 2000 V and enters a magnetic field of 5.0 mT at right angles. Find the radius of its path.

• Kinetic energy: ½mv² = eV, so v = √(2eV/m) = √(2 × 1.6 × 10⁻¹⁹ × 2000 / 9.11 × 10⁻³¹) ≈ 2.65 × 10⁷ m/s.
• Circular motion: r = mv/(Be) = 9.11 × 10⁻³¹ × 2.65 × 10⁷ / (5.0 × 10⁻³ × 1.6 × 10⁻¹⁹) ≈ 3.0 cm.

Answering six-mark questions

Extended response questions are marked on the quality of your physics and how clearly it is organised. Plan for thirty seconds before writing. List the key points, put them in a logical order, and use precise vocabulary. If the question asks you to describe an experiment, include the apparatus, what you measure, how you measure it, how you process the data, and how you reduce uncertainty. If it asks you to explain, link every observation to a cause.

Using mark schemes to learn

Mark schemes show exactly what examiners look for. After every past paper, compare your answers line by line. Notice the key phrases that earn marks, such as “constant phase difference” for coherence or “resultant force is zero” for equilibrium. Collect these phrases in a notebook and use them in your own answers. Examiner reports, published after each series, explain the common errors, which is useful advice that many students never read.

Looking after yourself

Revision works best when you are rested. Aim for steady sessions of 30 to 50 minutes with short breaks, regular sleep, and some exercise. Cramming the night before an exam rarely helps physics, because the subject depends on understanding and practice rather than memorising facts.

Common mistakes

• Rereading notes instead of testing yourself.
• Avoiding weak topics because they feel uncomfortable.
• Doing past papers without marking them carefully.
• Leaving maths skills to chance when they make up a large share of the marks.

Practice questions

Try each one before opening the answer.

Frequently asked questions

How many hours a week should I revise A level Physics?

It varies, but steady practice of several hours a week through Year 13, rising before exams, works well for most students. Consistency matters more than total hours.

When should I start past papers?

Start topic questions as soon as you finish each topic, and full papers once you have covered most of the content, usually in the spring of Year 13.

Key takeaways

• Test yourself rather than rereading.
• Practise synoptic questions that link topics.
• Plan six-mark answers before writing.
• Learn from mark schemes and examiner reports.
• Rest well; steady work beats cramming.

Building a revision timetable

Start by listing every topic on your specification and rating your confidence in each from one to five. Give the lowest-rated topics the most time, but revisit strong topics regularly so they stay fresh. A good weekly pattern mixes one new topic, one review topic and one past paper section. Spacing your practice like this, and mixing topics within a session, helps you remember for longer and prepares you for exams that jump between topics.

Keep a log of every mistake you make in practice, with the topic, the reason and the correct method. In the final weeks, this log becomes your most valuable revision resource, because it targets exactly the gaps that cost you marks.

Active recall techniques that work in physics

• Blank page recall: write everything you know about a topic from memory, then check your notes and fill the gaps.
• Explain it aloud: teach a concept to a friend, a family member or an empty room. Gaps show up quickly.
• Derive, do not memorise: derive equations such as v = √(GM/r) for orbits from first principles. Understanding the derivation makes the result stick.
• Flashcards for definitions: exact definitions, such as the volt or the Young modulus, are worth easy marks.

The final four weeks

In the last month, shift from learning to performing. Sit full papers under timed conditions, ideally at the same time of day as the real exam. Mark them strictly, update your mistake log, and spend the following session fixing the errors you found. Review definitions and practical methods daily in short bursts. In the last few days, ease off new material and focus on rest, your summary sheets and confidence. Walk into the exam having practised the real thing many times, and it will feel familiar.

If one topic keeps slipping despite your best efforts, that is the moment to ask for help, from a teacher or a tutor, rather than hoping it will not come up.
