There is no single correct starting date. The best timeline depends on the student's mathematical background, confidence with unfamiliar problems and other admissions commitments. However, preparation is usually stronger when it begins with general problem solving before becoming paper-driven.

Short answerFor a student seriously considering Cambridge Mathematics or another course using STEP, gentle preparation during Year 12 is valuable. More structured work can then develop through the application year, with full-paper preparation concentrated after an offer where appropriate.

Year 12: build the underlying habits

Early work should not look like weekly three-hour mock examinations. The aim is to become comfortable spending time on one demanding problem, trying examples, drawing a diagram and persisting when the first method fails.

Useful early activities include:

  • the free STEP Support Programme foundation modules;
  • selected older STEP questions matched to material already studied;
  • writing complete solutions rather than only checking final answers;
  • reviewing alternative methods; and
  • keeping a record of ideas that repeatedly cause difficulty.

Students do not need to wait until every Further Mathematics topic has been taught. Questions can be selected around accessible content while the broader problem-solving habits develop.

Summer before Year 13: establish consistency

A small, regular commitment is more useful than an intensive burst followed by several months without practice. One or two carefully chosen questions each week, followed by proper review, can reveal whether STEP preparation is progressing.

This is also a good time to distinguish content gaps from problem-solving gaps. If the student cannot begin because a technique has not been learned, repair the content. If all the required mathematics is known but the route remains hidden, practise representation, special cases and purposeful experimentation.

Autumn of Year 13: balance the admissions workload

Applicants may also be preparing for TMUA and Cambridge interviews. STEP should not disappear completely, but it does not always need to dominate. Maintain a modest stream of extended problems so the style remains familiar while shorter-term assessments receive the necessary attention.

At this stage, a student should increasingly be able to present a coherent solution, respond to hints and explain why a method works. These habits support both STEP and mathematical interviews.

Offer-holder period: move towards examination performance

Once STEP becomes a confirmed offer condition, preparation should become more systematic. Use the current specification and official information from OCR, then build a plan across STEP 2, STEP 3 and school examinations.

A sensible sequence is:

  1. diagnose topic and question-type strengths;
  2. complete selected questions without time pressure;
  3. practise choosing questions from a full paper;
  4. introduce timed groups of questions; and
  5. complete full papers with detailed marking and review.

Preserve recent papers until full-paper work will teach something meaningful. Completing them too early can remove the best realistic mocks without building the skills needed to benefit from them.

What if preparation begins late?

A late start does not make improvement impossible, but prioritisation matters. Begin with a diagnostic selection rather than attempting papers indiscriminately. Identify which broad areas provide the best opportunity for complete solutions and which recurring habits—such as abandoning work too quickly or failing to check cases— can be improved across many questions.

Use the STEP question database to select work by paper, year or topic. The purpose is not to predict the exact examination, but to obtain varied practice efficiently.

Signs that preparation is becoming effective

  • The student can work productively for longer before asking for a hint.
  • Initial experiments are chosen for a reason rather than at random.
  • Hints are incorporated instead of merely acknowledged.
  • Solutions contain clear definitions, cases and conclusions.
  • Review identifies transferable ideas rather than only isolated mistakes.
  • Question choice becomes more deliberate during timed work.
The central principleStart with the skills the examination requires, then introduce the examination conditions. Early preparation should create stronger mathematicians; later preparation should help those mathematicians produce their best script.
