How to Get an A or A* in A Level Physics: A Practical Guide for Future Applicants
A Level Physics is one of the most respected, demanding and useful A Levels you can take, especially if you are considering university courses such as Physics, Engineering, Natural Sciences, Computer Science, Medicine, Architecture or Economics. It is also a subject where small gaps in understanding can quickly become major obstacles. If you are preparing for A Level Physics, or deciding whether it is the right choice for you, working with The Profs A Level Tutors can help you build the subject knowledge, exam technique and confidence needed to aim for the highest grades.
Getting an A or A* in A Level Physics is not about memorising a few equations the night before an exam. It requires consistent work, strong mathematical fluency, clear practical understanding and the ability to apply concepts in unfamiliar situations. The best students do not simply know the content. They know how to use it.
This guide breaks down the key habits, revision methods and preparation strategies that can help prospective A Level applicants start strongly and progress towards top grades.
Why A Level Physics is challenging
Physics at A Level is a significant step up from GCSE. At GCSE, many questions test whether you can recall definitions, use standard equations and explain familiar processes. At A Level, you are expected to think more independently. You need to interpret data, link different areas of the course and use maths to explain physical relationships.
You may study topics such as mechanics, waves, electricity, particles, radiation, materials, fields, thermal physics, nuclear physics and practical methods. The exact structure depends on your exam board, but the underlying challenge is the same: you need to understand both the theory and the reasoning behind it.
This is why A Level Physics is so highly valued by universities. It shows that you can think analytically, handle abstract ideas and solve complex problems under pressure.
Start by understanding your specification
One of the most useful things you can do before or at the start of Year 12 is read your exam board specification. This is the document that tells you exactly what can be assessed.
Do not treat the specification as something only teachers need. It should become your revision checklist. Go through each topic and ask yourself:
What do I need to know?
What equations do I need to use?
What practical skills are assessed?
Which topics connect to each other?
Where am I already confident?
Where will I need extra support?
AQA, Edexcel and OCR all structure Physics slightly differently. Some boards include optional topics, while others place more emphasis on particular practical or contextual approaches. Knowing your specification early helps you avoid wasting time on material that is interesting but not directly assessed, while still leaving room for wider reading if you are applying for competitive university courses.
Build your maths early
A Level Physics is not just a science subject. It is also a mathematical subject. If your algebra is weak, your Physics will feel much harder than it needs to.
You should be comfortable rearranging formulae, working with standard form, interpreting graphs, calculating gradients, using trigonometry, handling units and understanding proportional relationships. As the course progresses, you may also encounter more advanced ideas that benefit from mathematical confidence.
If you are also taking A Level Maths, the two subjects can support each other well. If you are not taking Maths, you will need to be especially deliberate about keeping your quantitative skills sharp.
A good habit is to treat every calculation as a reasoning task, not just a number exercise. Before you begin, ask: what quantity am I trying to find, what information have I been given, what equation links them, and what units should my answer have?
This reduces careless errors and improves your ability to tackle unfamiliar exam questions.
Use the traffic light method
A common mistake in Physics revision is spending too much time on topics you already like. This feels productive, but it rarely leads to the biggest improvement.
Instead, use the traffic light system:
Green: topics you can explain and apply confidently
Amber: topics you understand partly but still make mistakes on
Red: topics you avoid or cannot yet explain clearly
Start with the red topics. These are usually where the most marks are being lost. Then move to amber topics, using exam questions to check whether your understanding is secure. Keep green topics ticking over through regular short practice, so they do not fade.
This approach is especially useful in Physics because the subject is cumulative. Weaknesses in forces, electricity or waves can reappear in later topics. The earlier you identify gaps, the easier they are to fix.
Practise past papers before you feel ready
Many students wait until they have “finished revising” before attempting past papers. This is usually too late.
Past papers are not just a final test. They are one of the best revision tools available. They show you how examiners phrase questions, what command words mean and how marks are awarded.
When you complete a question, do not only check whether your final answer is right. Study the mark scheme carefully. Look at where each mark comes from. Did you use the correct equation? Did you include the right unit? Did you explain the physical principle clearly? Did you justify your answer when asked?
Physics mark schemes can be precise. You may understand the topic but still lose marks because your explanation is vague or incomplete. Regular exam practice helps you write in the style the examiner expects.
Learn the command words
A Level Physics questions often use command words such as calculate, explain, determine, describe, justify, estimate or show that. Each word gives you a clue about the type of response required.
For example, “calculate” usually means you need to use numerical information and show your working. “Explain” means you need to link a cause to an effect. “Justify” means you need to support a conclusion with evidence or reasoning.
This sounds simple, but it matters. Many students lose marks because they answer the question they expected, not the question actually asked.
Before writing, pause and identify the command word. Then shape your answer around it.
Take practical work seriously
Practical skills are central to A Level Physics. Even when you are not physically in the laboratory, you may be assessed on experimental methods, uncertainty, accuracy, precision, graph work and data analysis.
You should understand standard practicals, know why particular equipment is used and be able to explain how to reduce error. You also need to be confident with units, significant figures and uncertainty calculations.
A useful revision method is to summarise each required practical in a simple format:
Aim
Equipment
Method
Variables
Sources of error
How to improve accuracy
What the graph should show
What the result means
This helps you prepare for practical-based questions without relying on memorisation alone.
Use visual revision properly
Physics contains many abstract ideas, so visual revision can be powerful. Mind maps, diagrams, flowcharts and flashcards can all help, but only if they are active.
Do not simply copy textbook diagrams. Recreate them from memory. Label forces, fields, circuit components or wave properties without looking. Then check what you missed.
Flashcards are useful for definitions, equations, units and common explanations. Mind maps are better for linking topics. For example, circular motion can connect to forces, fields, energy and mathematical modelling.
The aim is not to make beautiful notes. The aim is to retrieve information quickly and accurately.
Explain concepts to someone else
One of the best tests of understanding is whether you can teach the idea to another person.
Try explaining momentum, interference, electric fields or nuclear decay without using your notes. If you cannot explain a concept clearly, you probably do not understand it fully yet.
This technique is particularly effective for Physics because it forces you to organise your thinking. It also reveals hidden gaps. You may find that you can use an equation but cannot explain why it works, or that you remember a definition but cannot apply it to a practical situation.
Teaching is not a replacement for exam practice, but it is a strong way to deepen understanding.
Read beyond the course if you are aiming high
If you are applying for competitive university courses, especially Physics, Engineering, Natural Sciences or related subjects, wider reading can strengthen both your understanding and your application.
This does not mean racing ahead into university-level material without support. It means exploring Physics in a thoughtful way. You might read accessible books, attend lectures, watch university talks, enter competitions or explore topics such as quantum mechanics, astrophysics, particle physics, materials science or renewable energy.
Supercurricular work helps you see Physics as more than an exam subject. It also gives you stronger material for personal statements and interviews.
Keep your routine realistic
The students who succeed in A Level Physics are rarely those who revise in dramatic last-minute bursts. They are usually the ones who work steadily.
A strong weekly routine might include:
Reviewing class notes soon after each lesson
Completing practice questions on the current topic
Revisiting one older topic each week
Updating your traffic light list
Correcting mistakes from marked work
Doing short equation and definition recall
Attempting timed questions as exams approach
Small, consistent study sessions are usually more effective than occasional long sessions. Physics rewards repeated exposure. Each time you return to a topic, the ideas become more familiar and easier to apply.
Key takeaways
A Level Physics is difficult, but it is manageable with the right approach. Know your specification, strengthen your maths, practise past papers early and pay attention to practical skills. Do not avoid weak topics. Identify them, break them down and tackle them systematically.
For prospective A Level applicants, the best time to start preparing is before the course feels overwhelming. A strong foundation in Year 12 can make Year 13 far more manageable, especially if you are aiming for an A or A*.
Physics can open doors to some of the most competitive and rewarding university pathways. It builds problem-solving, precision, resilience and analytical thinking. These skills matter far beyond the exam hall.
