STEP Maths for IB Students: Bridging the Gap to Cambridge

The Sixth Term Examination Papers (STEP) are required by the University of Cambridge as an offer condition for Mathematics and are sometimes required or recommended for Warwick. If you are studying the International Baccalaureate and aiming for a Cambridge Maths offer, this guide explains the specific content gaps between IB HL Maths and STEP, and how to bridge them effectively.

What Is STEP and Who Needs It?

STEP is a paper-based mathematics examination set by Cambridge Assessment Admissions Testing. There are two papers: STEP 2 and STEP 3 (STEP 1 was discontinued). Each paper is 3 hours long with 12 questions — 8 in pure mathematics, 2 in statistics, and 2 in mechanics. You answer 6 questions of your choice. Cambridge Maths typically requires STEP 2 at grade 1 or above as an offer condition. Some other Cambridge courses and Warwick Maths may also include STEP conditions. STEP is sat in June, alongside A-level exams.

Unlike the TMUA (which is sat in October for interview shortlisting), STEP is a final condition of your offer. You must achieve the required grade to secure your place. It is one of the most demanding undergraduate mathematics entrance examinations in the world — questions require extended, rigorous written solutions, not multiple choice.

What IB HL Maths Covers Well

IB Maths Analysis and Approaches HL provides solid preparation for the pure mathematics core of STEP: calculus (differentiation, integration, differential equations), algebra (complex numbers, matrices to some extent, proof by induction), trigonometry, and probability. Students with strong IB Maths AA HL grades have a good foundation to build on.

The Key Gaps Between IB HL Maths and STEP

Several STEP topics are either absent or underrepresented in IB Maths AA HL:

• Mechanics: STEP includes two mechanics questions per paper based on Newtonian dynamics, projectiles, moments, and energy/work. IB Physics covers some mechanics but not the calculus-based mechanics depth needed for STEP. You need to study the A-level Further Maths mechanics modules separately.
• Further Pure Mathematics: STEP 2 and 3 include topics such as polar coordinates, hyperbolic functions, vectors in 3D, matrices beyond 2×2, and complex number geometry that extend beyond IB HL Maths.
• Statistics: STEP statistics questions are based on the A-level Statistics modules (discrete and continuous distributions, hypothesis testing at A-level depth). IB Maths includes statistics but the specific distribution depth differs.
• Extended Proof Writing: STEP demands multi-page written proofs in a clear mathematical style. IB Maths HL includes some proof but not at the depth or length STEP requires.

What Grade 1 on STEP 2 Actually Requires

Many students — and some school teachers — have an inaccurate mental model of what Grade 1 on STEP 2 requires. The grading works as follows: STEP 2 has 12 questions. Candidates attempt at most 6. Each question is marked out of 20. Grades are assigned based on total marks: roughly speaking, Grade S (outstanding) requires approximately 90+ marks, Grade 1 requires approximately 60–85 marks, Grade 2 requires approximately 40–59 marks.

Grade 1 — the standard Cambridge offer condition — therefore requires fully correct solutions to approximately 3 questions out of the 6 you attempt, with partial credit on others. This is achievable with consistent preparation but requires significantly more mathematical depth than A-level or IB HL Further Maths.

The most common mistake in STEP preparation is attempting too many questions in practice sessions before solutions are thorough enough. STEP rewards depth: three completely correct solutions score higher than six half-correct solutions. Practise completing questions fully before moving on, and treat partial solutions as diagnostic tools for identifying where your mathematical toolkit has gaps rather than as acceptable exam performance.

IB HL Further Maths students have a stronger starting point for STEP 3 than HL Maths AA students, particularly in complex numbers and matrices. However, the mechanics gap remains significant for all IB students and is worth addressing early.

How Leading Tuition Can Help with STEP Preparation

Recommended Resources for IB Students Preparing for STEP

• Cambridge STEP Support Programme (free at maths.org/step) — 10 modules for STEP 2, 11 for STEP 3. Especially useful for IB students as it introduces content systematically.
• Advanced Problems in Mathematics by Stephen Siklos — 65 STEP-style questions with worked solutions. Essential.
• A-level Further Maths textbooks (MEI or Edexcel) — for mechanics and further pure content gaps. Read the relevant chapters as content supplements, not full exam preparation.
• Past STEP papers (free from maths.cam.ac.uk) — from Year 2 onwards as full timed practice.

Preparation Timeline for IB Students

Start of Year 13 (September): Read the STEP specification. Identify content gaps vs your IB syllabus. Begin Cambridge STEP Support Programme from module 1.
October–February: Cover mechanics modules using A-level Further Maths materials. Continue STEP Support Programme. Attempt some STEP 2 pure questions without time pressure.
March–April: Begin timed practice on full papers. Prioritise pure mathematics questions initially.
May–June: Full timed 3-hour sittings once per week. Review solutions against mark schemes in detail. Identify question types you are consistently losing marks on.

Students who achieve STEP grade 1 typically spend 15–20 hours per week on STEP preparation during the final months. This is a demanding commitment alongside IB final exams — plan your overall Year 13 timeline carefully. See also our guide on STEP and TMUA together for Cambridge Maths.

Frequently Asked Questions

Does Cambridge Maths require STEP for international IB students?

Yes. Cambridge Maths applies the same admissions requirements to all applicants regardless of nationality or curriculum. International students studying the IB must meet the STEP 2 grade 1 condition just as A-level students do. STEP is sat in June, administered by Cambridge Assessment Admissions Testing at approved centres worldwide. The key difference for IB students is that the IB curriculum has specific gaps relative to A-level Further Maths that need to be addressed during preparation.

What are the biggest content gaps between IB Maths HL and STEP?

The main gaps are: (1) Mechanics — STEP includes calculus-based Newtonian mechanics not covered to this depth in IB. (2) Further Pure — polar coordinates, hyperbolic functions, 3D vectors, and matrices beyond 2x2 extend beyond IB HL Maths. (3) Statistics — STEP uses A-level Statistics distributions that differ slightly from IB. (4) Extended proof writing — STEP requires multi-page formal mathematical proofs at a depth beyond IB HL. Plan to spend six to nine months addressing these gaps.

When should IB students start preparing for STEP?

Start at the beginning of Year 13 (September). This gives you nine months before the June sitting. Begin with the Cambridge STEP Support Programme modules to systematically cover content gaps, then move to timed past paper practice from March onwards. Students who start in January or later consistently find the content preparation period too short and underperform in the mechanics sections specifically.
