How to get an A in A-level Physics
Dr Lavan Ganeshkumar, PhD · updated 4 October 2026
An A in A-level Physics comes from three things: understanding the topics rather than memorising them, practising a lot of exam questions, and learning exactly how the mark scheme awards marks. It is usually not about studying more hours, but about studying differently.
Grade boundaries change every year, so aim for secure marks across the paper rather than a target number.
The topics that decide the grade in Physics
Across the course, the topics that most often separate grades are mechanics and SUVAT, circuits and internal resistance, waves and interference, fields and capacitors, nuclear physics, and practical skills. They are heavily examined, they build on earlier ideas, and they are where students most often stall.
How marks are lost
Students lose marks on physics by not writing the equation and substitution, dropping units, rounding too early, and giving a description where the scheme wants a reason.
"It gets hotter so the resistance goes up" scores little, while "the lattice ions vibrate more, so electrons collide with them more often, so resistance increases" scores the marks.
A plan that works
This is the loop to run on every topic.
- Understand the principle in words before the equation.
- Recall definitions and the equations that are not on the sheet.
- Do calculation questions by topic, writing equation, substitution, answer and unit every time.
- Practise practical-skills and data questions, because they carry real marks.
If you are on a C, a B or an A
On a C, fix understanding first, then questions. On a B, the gap is usually precision: exact wording or methods and fewer slips. On an A aiming higher, the gap is harder unfamiliar questions and consistency, so do the toughest questions and mark strictly.
Where Trayna fits, and where it does not
Trayna is a 24/7 online tutor in your pocket, on your tablet and on the web. Dr Lavan teaches you the topics in the app any time, anywhere, and an adaptive plan reinforces them each day from now to your exam. It is there for students who cannot afford 1-to-1 tutoring, and it is built to act like a 1-to-1 tutor: it teaches, it checks, and it adapts to how you are doing. The aim is that you really understand the subject and are prepared for it, not just that you have revised it. It is A-level only, for Maths, Chemistry, Physics and Biology. Maths follows Edexcel; Chemistry, Physics and Biology follow AQA.
For Physics, Trayna follows AQA. The loop above is how it teaches: a short tutorial from Dr Lavan, questions straight away, and wrong answers come back later.
It is for both Year 12 and Year 13. Year 13 students already use it, and Year 13 topics are being added as current students need them while Year 12 is the most complete, so check your topics in the app. If you only want free past papers, PMT does that better than we do, and we would rather you used it.
Common questions
How do I get an A in A-level Physics?
Understand each topic rather than memorise it, practise calculations, practical-skills questions and extended explanations, and mark against the official scheme. Focus on mechanics and SUVAT, circuits and internal resistance, waves and interference, fields and capacitors, nuclear physics, and practical skills, where most grades are decided.
What topics are hardest in A-level Physics?
The ones students most often struggle with are mechanics and SUVAT, circuits and internal resistance, waves and interference, fields and capacitors, nuclear physics, and practical skills. Giving them extra time and doing questions on them is the quickest route up.
How do I go from a C to an A in A-level Physics?
Find why you lose marks, fix the topics you only half understand, then practise questions marked strictly against the scheme and revisit each topic on a schedule.
What are the grade boundaries for A-level Physics?
They change every year and depend on the paper difficulty, so there is no fixed number. Aim to be secure across every topic and paper instead of a target score.
Which exam board does Trayna Physics follow?
AQA. If you sit a different board, check the topic list in the app first.
Trayna does this automatically. You enter your subjects, your exam dates and how long you have each day, and it builds the route from today to those exams, then adapts it as you go. Maths follows Edexcel; Chemistry, Physics and Biology follow AQA.
