When Should You Start A Level Maths Past Papers? (And Will You Run Out?)

Past papers are the best practice there is, and there are more of them than you might think. When to start them, which order to do them in, and how to mark them like an examiner.

Past papers are the best practice there is for an exam, so two questions come up every year: when should I start them, and will I run out? The short answers: start once you have covered enough of the course, and no later than when you have finished it. And no, you almost certainly won't run out.

Sound familiar?
  • You did a past paper early and the score knocked your confidence
  • You are worried you will run out of papers before the exam
  • You mark your own papers, and the scores look better than your mocks

This guide covers when full papers start to help, how many there really are and which order to do them in, and how to mark them so the score means something.

Why not start them straight away?

Because a paper done too early teaches you much less than it seems to.

If past papers are the best practice, it's tempting to start them as early as you can. But a past paper is written to test content you already know reasonably well. If you start one before you do, one of two things tends to happen, and neither is real progress.

You learn the topic through the exam questionIt takes a very long time. Exam questions combine several ideas at once and do not isolate the one skill you are missing, so it is an inefficient way to learn.
You get shown how to do that questionIt feels like progress, but without the understanding underneath, the method will not transfer to a slightly different question next time.

Exam questions are not designed to teach. They are designed to assess.

There is a cost to confidence as well. A full paper attempted before you are ready means question after question you cannot do yet, and that tends to put students off papers just when they need them most.

Part 01

When to start

Between having covered enough of the course and having finished it.

Plenty of students leave past papers too late, so this is about finding the sweet spot rather than holding off. You want to have covered enough content for a paper to be a fair test, and for most students the latest to start full papers is when you have finished all the course content. If you have, early April is a good time to be starting.

You don't have to wait for everything, either. If your school finishes the pure content before the statistics and mechanics, you can start the pure papers then. The papers from one exam series don't have to be done together: do the pure papers when you are ready for them, and the applied ones when you have finished those topics.

  1. Year 12 and early Year 13Mixed exam questions, and AS papers
    A regular mixed set of exam questions on the topics you have finished. AS papers count here too, and in early Year 13 as well (more on that below).
  2. As each part of the course is finishedThat part's papers
    Finished the pure content? Start the pure papers, timed, while you are still finishing the statistics and mechanics.
  3. By early April, if the content is doneFull papers in exam conditions
    Whole papers against the clock, each marked properly and its mistakes followed up.
  4. The last monthAbout three papers a week
    By now the content should be secure, and the papers are for technique, timing and finding where marks are still being lost.

When your school finishes the course matters, and it varies a lot. If you are doing mixed exam questions regularly through the year, starting full papers a bit later is not a big deal. But give yourself plenty of time, for two reasons: to practise in exam conditions, and to find out which topics you still need to work on while there is time to work on them.

AS papers are a good source of exam questions in Year 12, and early in Year 13. They won't cover the new Year 13 content, but they let you practise the topics you are about to extend, and get more confident with them first. Plenty of AS questions could just as easily come up on a full A level paper, too.
Don't wait for past papers to work on your exam technique. Regardless of when you start full past papers, every exam question you do through the year is a chance to practise it: setting out your working, answering exactly what was asked, checking. That is all in our guide to A Level Maths exam technique.
Part 02

Will you run out?

Almost certainly not, but there is a catch worth knowing about.

There are more A Level Maths papers than most students expect. For each board:

8exam series sat since 2018, including the autumn series of 2020 and 2021
24full A level papers from those series, three per series
50+papers in all, once you add the sample, mock and AS papers

The most diligent students might get through all of them, but most won't. The catch is a different one. If you have been doing exam questions all through the year, as you should, you will already have seen a fair few of the questions on the papers. That makes a past paper less useful for the thing you want it for in the last few months: finding out where you actually are now.

So it is worth thinking about the order you do them in.

Keep the most recent for last

Your board's latest papers are the most like the one you will sit, so leave them until closer to the exam. For the older ones, the order doesn't matter much.

Closest to your exam
Use the mock and sample papers

Each board has several mock papers and sample papers alongside the real ones. They are full papers in the right format, and good ones to use earlier.

More full papers
Try other boards' papers

The content is about 90 to 95% the same across boards, so if you ever did run short, there are plenty of papers from the other boards to have a go at.

If you run short
Worth knowingGrade boundaries from the covid years are different.There were no summer exams in 2020 or 2021, but there were real papers in the autumn of both years, sat by a small, unusual group of students, and their boundaries sit well below the years either side. June 2022 was graded deliberately low as well. To see roughly what grade a score would get you, compare it with a series from 2024 onwards. Our grade boundaries page marks which years are which.

Every board's papers, with mark schemes and examiner's reports, are on our past papers page.

Part 03

Mark it like an examiner

Because a generous score hides exactly what you need to fix.

When students send me papers they have marked themselves, I nearly always find a substantial number of marks they have given themselves that they would not have got in the exam. Here is how that happens, on one exam-style question and one of the most common ways to lose a mark.

The questionThe curve C has equation y = ¾x2. The point P on C has x-coordinate 1. Find the equation of the tangent to C at P, giving your answer in the form ax + by + c = 0, where a, b and c are integers. (4 marks)
Marked by the student
Handwritten working: dy/dx = 3/2 x, which is 3/2 at x = 1; y minus 3/4 = 3/2 (x minus 1); y = 3/2 x minus 3/4. A green tick on every line and 4/4 at the foot.

Every line ticked: 4 out of 4.The mark scheme's line was the same line, so it looked right.

Re-marked
The same working re-marked in red pen: the last line, y = 3/2 x minus 3/4, ringed with "ax + by + c = 0, integers?" and "not the form asked: A0", the last tick struck through, and the 4 crossed out with a 3 beside it.

The last mark goes: 3 out of 4.An example of how the marks might be split. The last one is for the answer in the form the question asked for.

The mark scheme's answer was 6x − 4y − 3 = 0. The student saw it was the same line as theirs and ticked it. But the question asked for that form, with integers, and the last mark is for getting there. Examiners' reports regularly mention this one. When you mark your own paper, check each answer against what the question asked for, not just against the number in the mark scheme. Those are exactly the marks a generous self-marker gives away.
