Quick Summary
Exams & practicals – About 70% exams, 30% practical skills tested in exams
Heavily mathematical – You MUST take A-Level Maths alongside Physics (about 40% is applied maths)
Big jump from GCSE – Much harder than GCSE Physics (you'll need at least a grade 7, ideally higher)
What's it actually like?
IN A NUTSHELL
A-Level Physics combines written exams with practical work. You'll study mechanics, electricity, waves, fields, particles, and more. The course is heavily mathematical – expect lots of equations, calculations, and problem-solving.
You'll do required practicals throughout the course (typically 12 core practicals), which get assessed through questions in your written exams rather than as separate coursework. The exams test both your understanding of physics concepts and your ability to apply maths to solve problems.
Critical requirement: You MUST take A-Level Maths alongside Physics. If you're not taking Maths A-Level, don't take Physics. About 40% of Physics is essentially applied mathematics.
You need to be genuinely interested in the "why" and "how" of the physical world, not just memorising facts.
You NEED strong maths: You must take A-Level Maths alongside Physics. If you're not taking Maths A-Level, don't take Physics. About 40% of Physics is essentially applied mathematics.
About the course
Is this for you?
Motion, forces, and energy
You'll study motion, forces, energy, and materials – learning how objects move and how forces affect them.
Waves, electricity, and magnetism
You'll explore light, sound, circuits, fields, and how electrical components work in real systems.
Advanced topics
Later in the course, you'll move on to particles, nuclear physics, and quantum ideas, plus thermal physics and astrophysics (depending on your exam board).
Practical work
Alongside theory, you'll carry out experiments and learn how to analyse data, write up methods, and evaluate results. These skills are assessed through exams and practical endorsements.
Physics is a good choice if you:
Want to understand how the universe actually works
Enjoy solving problems that combine concepts and calculations
Comfortable with lots of mathematics (and I'm taking A-Level Maths)
Like the idea of lab work and practical experiments
Can visualise abstract scenarios (forces, fields, particle interactions)
Don't mind when things don't make intuitive sense immediately
Mathematical application - Use algebra, trigonometry, and calculus constantly, strengthening your ability to apply maths to real problems.
Problem solving - Physics problems often require multiple steps, drawing on different topics, and thinking creatively.
Experimental skills - Learn to design experiments, collect accurate data, analyse uncertainty, and draw valid conclusions.
Scientific thinking - Develop the ability to construct models, make predictions, test them, and refine your understanding.
Data analysis - Working with graphs, statistics, and experimental data becomes second nature.
Logical reasoning - Build explanations from first principles and spot flaws in arguments.
The GCSE jump is massive. A-Level Physics is much harder than GCSE. If you found GCSE Physics difficult, think very carefully. You'll need at least a grade 7, preferably higher.
It's content-heavy. There's a lot to learn, equations, concepts, derivations, practical techniques. You can't cram this subject.
Some parts are counterintuitive. Quantum mechanics and relativity challenge your everyday understanding of reality. You need to be comfortable with that.
Practical work matters. You can't just be good at the theory. You need to be able to carry out experiments carefully and analyse data properly.
✨ Silver lining: Physics is considered one of the most rigorous A-Levels. Universities and employers know it's tough, which works in your favour.
Maths + Physics + Chemistry = The ultimate STEM combination
Maths + Further Maths + Physics = For physics/engineering at top unis
Maths + Physics + Computer Science = For tech/engineering routesPhysics success comes from understanding concepts deeply and practising problem-solving.
Here's how to excel:
Master the maths – Keep your maths skills sharp – rearranging equations, trigonometry, algebra. Physics problems are really maths problems in disguise. Practice both subjects together.
Understand, don't memorise – Focus on understanding why equations work, not just memorising them. If you understand the physics, you can derive equations you've forgotten in exams.
Take practicals seriously – Actually do the experiments properly – don't just copy results. Understanding experimental techniques and uncertainties is crucial for exam questions.
Practice past papers – Physics exam questions follow patterns. Do lots of past papers under timed conditions to get familiar with question styles and improve your speed.
Physics graduates can go on to work in:
Engineering
Research
Data science
Finance
Software development,
Teaching
Medical physics
Renewable energy
Aerospace, and more.
The problem-solving and analytical skills are valued across industries.
Physics A-Level is essential for degrees in:
Physics degrees
Engineering (especially Mechanical, Aerospace, Electrical)
Astrophysics
It is also highly recommended for degrees in:
Materials Science
Natural Sciences
Computer Science
Many medical schools value it as evidence of scientific and mathematical thinking.
Top tip: Most Physics degrees also require A-Level Maths. Further Maths is often recommended too.
Ask yourself:
Did I enjoy GCSE Physics and find it manageable (grade 7+)?
Am I taking A-Level Maths? (If not, don't take Physics)
Am I genuinely curious about how things work at a fundamental level?
Can I handle lots of equations and mathematical problem-solving?
Am I comfortable with practical experiments and data analysis?
Do I want to keep engineering, physics, or other STEM options open?
If you're answering yes to most of these, Physics could be an excellent choice.
