Many students approach the Sixth Term Examination Paper believing it is simply a harder version of A-Level Maths. It is not. STEP tests mathematical thinking — the ability to construct arguments, spot structure, and work through unfamiliar problems without a template to follow. Students who have coasted through A-Level by learning methods and applying them will find STEP genuinely disorienting at first. That is not a reflection of their ability; it is a reflection of how different the demand is. Structured preparation, ideally with an experienced tutor who knows the paper well, makes a significant difference — not because it shortcuts the thinking, but because it teaches you how to think in the way STEP rewards.
The gap between A-Level and STEP is wider than most applicants anticipate. At A-Level, a student who understands the syllabus can usually identify which technique a question is asking for within a few seconds. STEP questions are deliberately constructed to resist that reflex. A question may draw on pure mathematics, mechanics, and probability simultaneously, or it may present a familiar topic in an unfamiliar way that requires you to build your own method from first principles.
The other shock is the time pressure. You have three hours to attempt a small number of questions, and the expectation is not that you will finish — it is that you will demonstrate sustained, high-quality mathematical reasoning on the questions you do attempt. Students who have never worked in that mode before often freeze, rush, or abandon questions too early. Learning to manage that environment is a skill in itself, and it takes deliberate practice to develop.
There are two STEP papers in current use: STEP 2 and STEP 3. STEP 2 is based on A-Level Mathematics with some Further Mathematics content. STEP 3 draws more heavily on Further Mathematics. Cambridge typically requires both; other universities may specify only STEP 2. Each paper lasts three hours and contains twelve questions. You are expected to attempt no more than six, and only your best answers count.
Questions are divided into three sections: pure mathematics, mechanics, and probability and statistics. The pure section contains eight questions; mechanics and statistics contain two each. Most candidates focus primarily on pure, but having at least one or two mechanics or statistics questions prepared as options is a sensible strategy.
The questions are long, multi-part, and cumulative — later parts often depend on results established earlier. This structure rewards candidates who can hold a thread of reasoning across several steps, and it punishes those who guess or skip ahead without understanding why an earlier result is true.
Each question is marked out of 20. Your six best answers contribute to a total out of 120, which is then converted to a grade: S (Outstanding), 1, 2, 3, or U. Cambridge's standard conditional offer for Mathematics typically requires grades of 1,1 in STEP 2 and STEP 3, though this varies by college and year. Some colleges ask for S,1. Warwick, Imperial, and Bath also use STEP as part of their admissions process, and their grade requirements differ — usually a grade 1 or 2 in STEP 2.
It is worth understanding that a grade 1 does not require perfection. A candidate who produces four or five genuinely good solutions, with clear reasoning and accurate working, can achieve a grade 1 without completing every part of every question. Universities are looking for evidence of mathematical maturity, not mechanical completeness.
Most students who perform well begin structured STEP preparation in January or February of Year 13, giving themselves four to five months before the June sitting. Starting earlier — in the autumn term — is beneficial if a student is also sitting STEP 3 or has gaps in their Further Mathematics knowledge to address first.
A productive preparation period typically moves through three phases: building the underlying mathematical fluency needed for STEP-style problems, working through questions by topic to develop technique and confidence, and then moving to timed full-paper practice in the final six to eight weeks. Jumping straight to past papers without the first two phases is one of the most common preparation mistakes, and it tends to produce frustration rather than progress.
Our STEP tutors are mathematicians who know the papers in depth — not generalist tutors who have glanced at a few past questions. When we work with a student, we begin by assessing where they actually are: which areas of the syllabus are secure, which are shaky, and how they currently approach an unfamiliar problem. From that, we build a structured programme rather than working through past papers at random.
Sessions focus on developing the habits that STEP rewards: reading a question carefully before writing anything, identifying the mathematical structure being tested, constructing a clear argument rather than a sequence of calculations, and knowing when to move on. We also work on the psychological side of sitting a high-stakes paper — how to stay composed when a question is not immediately clear, and how to make strategic decisions about which questions to attempt.
We work with students across the UK, including those applying to Cambridge, Warwick, Imperial, and Bath. Our tutors understand what each institution is looking for and can tailor preparation accordingly.
How far in advance should I start preparing for STEP?
For most students, January of Year 13 is a sensible starting point, giving four to five months before the June sitting. If you are sitting both STEP 2 and STEP 3, or if your Further Mathematics knowledge needs strengthening first, starting in the autumn term of Year 13 is advisable. Beginning earlier gives you time to build genuine understanding rather than rushing through past papers under pressure.
Can STEP be retaken if I do not achieve the required grade?
STEP is sat once per year, in June. If you do not meet your offer conditions, you cannot resit in the same cycle. Some students defer their university entry and resit the following year, but this is a significant decision. The stronger approach is to prepare thoroughly the first time, with enough lead time to address weaknesses before the sitting.
What does a competitive score look like at Cambridge and other universities?
Cambridge Mathematics typically requires 1,1 in STEP 2 and STEP 3, with some colleges asking for S,1. Warwick and Bath generally require a grade 1 or 2 in STEP 2. A grade 1 is achievable without answering every part of every question — four or five well-argued solutions with clear reasoning will usually be sufficient, depending on the year's grade boundaries.
What resources beyond past papers are useful for STEP preparation?
Past papers are essential, but they work best once you have built the underlying skills. The STEP Support Programme produced by Cambridge offers structured problem sets organised by topic and difficulty, which are particularly useful in the early stages. Stephen Siklos's Advanced Problems in Mathematics is also widely recommended. Working with a tutor who can give feedback on your reasoning — not just your answers — adds something that self-study resources alone cannot replicate.
