How to revise A-level Maths
Dr Lavan Ganeshkumar, PhD · updated 4 October 2026
A-level Maths rewards understanding and practice, not rereading. The revision that works has four parts, in order: learn the idea, recall it from memory, do exam questions on it, and mark them against the scheme.
Each part uses a different skill, and skipping one is the usual reason a grade stalls.
The four-step method
Run this loop on each Maths topic.
- Study a worked example, then cover it and redo it.
- Do questions by topic until the method is automatic.
- Move to mixed-topic questions, because exams do not say which topic they test.
- Mark your own working and sort each lost mark into method or accuracy.
What to practise in Maths
The question types that carry the most marks are worked methods, mixed-topic questions and full timed papers. Practise each by topic first, then mixed, then in full timed papers.
The mistakes to avoid
Students lose marks in maths by skipping steps, making sign and algebra slips, not reading what the question asks for, and not showing the method.
A wrong answer with correct working still earns method marks, and a correct answer with no working can lose them. The marks are in the written steps.
A daily routine
Twenty minutes learning one small topic, twenty minutes answering questions on it without notes, five to ten minutes marking and writing down every lost mark. Next day, five minutes of recall on yesterday before starting something new.
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.
In Maths Trayna follows Edexcel, and it runs this routine for you.
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 revise A-level Maths?
Learn the idea, recall it from memory, do exam questions on it without notes, and mark them against the official scheme. Repeat on a schedule.
What is the best way to revise Maths?
Active methods: recall from blank pages and exam questions, not rereading. For Maths, focus on worked methods, mixed-topic questions and full timed papers.
How many hours should I revise Maths for?
A few focused hours a week outside lessons in Year 12, more in Year 13 and near exams. Active hours count, rereading does not.
What mistakes do students make in A-level Maths?
Students lose marks in maths by skipping steps, making sign and algebra slips, not reading what the question asks for, and not showing the method.
Which exam board does Trayna Maths follow?
Edexcel. Check the topic list in the app first if you sit a different board.
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.
