Ask a Year 12 class which subject gave them the biggest shock after GCSE and physics wins most years. It is rarely because the content is enormous — the specification is shorter than you would guess. It is because the exam tests a different skill from the one GCSE rewarded. GCSE physics mostly asked you to remember. A-Level physics hands you an unfamiliar situation and asks you to decide what to do, with at least 40% of the marks assessing maths skills along the way.
That difference is why the default revision method — read the notes, make the notes smaller, read them again — fails harder in physics than in any other subject. Here is what to do instead.
Why reading notes fails in physics
Notes are statements of what is true: definitions, equations, laws. But almost no marks are awarded for knowing what is true. They are awarded for choosing the right piece of physics for this situation, setting it up correctly, and carrying the maths through. That selection skill only develops one way: by facing situations and choosing, over and over.
Notes tell you what is true. The exam asks what happens next. Only problems train that.
So the core loop of physics revision is not read–condense–reread. It is attempt–check–reattempt, with notes demoted to a reference you consult when a problem exposes a gap.
The data booklet changes what "learning equations" means
You are given a data and formulae booklet in the exam, which students misread as "I do not need to learn the equations." What the booklet actually does is move the difficulty: since the formulas are free, the marks are in knowing which one applies and when it is allowed.
Take the suvat equations. The booklet lists , but it will not tell you that suvat only holds for constant acceleration — spotting that a question involves changing acceleration, so suvat is off the table, is the question. For every equation on your specification, build a small map: what each symbol means with its units, the conditions under which the equation is valid, and which other equations it connects to. That map is worth more than any set of notes, and it is exactly the thing the booklet does not give you.
Do problems in three passes
A method for turning worked examples into actual ability:
- Study a worked example line by line until every step is obvious — including why each step was chosen, not just what it does.
- Redo the same problem cold, from the question alone, a day later. This feels pointless and is not: most people discover they can no longer make the third step happen, and that discovery is the revision.
- Attempt a new problem on the same physics. Where you stall is your genuine gap — log it by topic, and let that log choose tomorrow's work.
Definitions are the cheapest marks on the paper
Physics mark schemes are pedantic about wording, and that is good news, because definition marks are the only ones you can bank in advance with certainty. "Rate of change of," "per unit," "work done per unit charge" — these phrases are the difference between the mark and no mark. Put every definition on your specification into flashcards and learn them close to verbatim. It is a rare piece of pure memorisation in this subject; take the free marks.
Required practicals are exam content, not a memory of a fun lesson
There are twelve required practicals across the two years, and they show up in the written papers — methods, graphs, and especially uncertainty. For each one, be able to state: the aim, the method in a few steps, what is plotted against what and what the gradient or intercept gives you, the main sources of uncertainty, and one concrete way to reduce each. Questions asking you to criticise or improve a method are testing exactly this list.
Six-markers want a chain, not an essay
Extended-response questions are marked holistically: the examiner is looking for a logical chain of correct physics, named and in order. Long paragraphs of good English wrapped around two physics points score worse than six blunt sentences that each contain one. Before writing, spend thirty seconds listing the chain — principle, consequence, consequence, conclusion — then turn each link into a sentence.
Sanity-check every answer
Physics gives you a lie detector no other subject has: reality. A car doing 400 m/s, a wire stretching by three metres, a current of 5000 A — each should trigger alarm bells and send you hunting for the dropped power of ten. Check the number is plausible and check the units come out right. Ten seconds per question, and it catches the most expensive class of error in the subject.

Frequently asked questions
Why is A-Level Physics so much harder than GCSE?
Because the skill being tested changes. GCSE physics largely rewards recalling facts and using single equations; A-Level presents unfamiliar multi-step situations and asks you to choose the right physics, justify it, and carry substantial maths through — at least 40% of the marks assess mathematical skills. Revision built on re-reading notes trains recall, not selection, which is why it stops working.
Do I need to memorise equations if there is a data and formulae booklet?
You still need to learn the equations — just differently. The booklet gives you the formulas, so the marks move to knowing what each symbol means with its units, the conditions under which each equation is valid (suvat only applies for constant acceleration, for example), and which equation a given situation calls for. That selection knowledge is not in the booklet.
How do I revise the required practicals for A-Level Physics?
Treat each of the twelve required practicals as examinable content. For every practical, learn the aim, the method in a few steps, what is plotted against what and what the gradient or intercept represents, the main sources of uncertainty, and a concrete improvement for each. Written-paper questions on practicals almost always draw from that list.
