# Sixth Term Examination Paper

The Sixth Term Examination Papers in Mathematics, often referred to as STEP, is currently a university admissions test for undergraduate courses with significant mathematical content - most notably for Mathematics at the University of Cambridge. Starting from 2024, STEP will be administered by OCR, replacing CAAT, who was responsible for administering STEP in previous years.
Being after the reply date for universities in the UK, STEP is typically taken as part of a conditional offer for an undergraduate place. There are also a small number of candidates who sit STEP as a challenge. The papers are designed to test ability to answer questions similar in style to undergraduate Mathematics.
The official users of STEP in Mathematics at present are the University of Cambridge, Imperial College London, and the University of Warwick. Since the 2025 entry application cycle, the STEP exams have been superseded by the TMUA exam at Imperial College London and the University of Warwick. Candidates applying to study mathematics at the University of Cambridge are almost always required to take STEP as part of the terms of their conditional offer. In addition, other courses at Cambridge with a large mathematics component, such as Economics and Engineering, occasionally require STEP. Candidates applying to study Mathematics or closely related subjects at the University of Warwick can take STEP as part of their offer. Imperial College London may require it for Computing applicants as well as Mathematics applicants who either did not take MAT or achieved a borderline score in it.
A typical STEP offer for a candidate applying to read mathematics at the University of Cambridge would be at least a grade 1 in both STEP 2 and STEP 3, though - depending on individual circumstances - some colleges may only require a grade 1 in either STEP. Candidates applying to the University of Warwick to read mathematics, or joint subjects such as MORSE, can use a grade 2 from either STEP as part of their offer. Imperial typically requires a grade 2 in STEP 2 and/or STEP 3.

## History

Before 2003, STEP was available for a wide range of subjects. In 1989, for instance, the full list of subjects offered was: Biology, Chemistry, Economics, English Literature, French, General Studies, Geography, Geology, German, Greek, History, Italian, Latin, Mathematics, Further Mathematics, Music, Physics, Religious Studies, Russian, and Spanish. STEP in Mathematics are the only ones now in use. Two (three prior to the discontinuation of STEP 1 in 2019) STEP in Mathematics are set each year, and are both sat during the school summer examination cycle (usually in June).

## Format

Until 2019, there were three STEPs: STEP 1, STEP 2 and STEP 3. Since the academic year 2019/20, STEP 1 has been phased out. There was no STEP 1 set in 2020 due to the COVID-19 pandemic, and it was later announced that from 2021, STEP 1 would no longer be set, with only STEP 2 and STEP 3 being available. The last STEP 1 was held in 2019.
Candidates may enter for as many as they wish, although this is often dictated by the STEP offers they hold. Each paper offers a selection of questions and there is no restriction on which can be answered. For each paper, candidates have three hours to complete their solutions. Whilst students are permitted to answer as many questions as they choose, they are advised to attempt no more than six, and their final grade is based on their six best question solutions. Each question is worth 20 marks, and so the maximum a candidate can score is 120.
For examinations up to and including the 2018 papers, the specification for STEP 1 and STEP 2 was based on Mathematics A Level content while the syllabus for STEP 3 was based on Further Mathematics A Level. The questions on STEP 2 and 3 were about the same difficulty. Both STEP 2 and STEP 3 are harder than STEP 1.
For the 2019 examinations onwards, the specifications have been updated to reflect the reforms in A Level Mathematics and Further Mathematics; in addition, the number of questions in each paper has been reduced. Specifically:
* The STEP 1 specification was based on A Level Mathematics, with some additions and modifications. The paper comprised 11 questions: 8 pure, and 3 further questions on mechanics and probability/statistics, with at least one question of the 3 on mechanics and at least one on probability/statistics. The June 2019 paper was the only STEP 1 paper to be sat under the new syllabus before the retiring of STEP 1.
* The STEP 2 specification is based on A Level Mathematics and AS Level Further Mathematics, with some additions and modifications. The paper comprises 12 questions: 8 pure, 2 mechanics, and 2 probability/statistics.
* The STEP 3 specification is based on A Level Mathematics and A Level Further Mathematics, with some additions and modifications. The paper comprises 12 questions: 8 pure, 2 mechanics, and 2 probability/statistics

## Practicalities

Since June 2009, graph paper has not been allowed in STEP as the test requires only sketches, not detailed graphs. Instead, all graphs should be sketched inside the answer booklets provided as part of a candidate's solution.
Since June 2018, the format of the answer booklet for the STEP Mathematics examinations has been updated to ensure that the paper is fully anonymised before it is marked. Candidates are issued with a 44-page booklet, of which 40 pages are available for writing out solutions and for rough work. Only one booklet per candidate is allowed unless a further booklet is required and has been formally requested as a result of specific access arrangements.
Candidates are advised to write their answers in black ink and draw pictures in pencil, although some flexibility is permitted with this. Candidates should not use green or red pen at any stage.
Calculators may not be used during STEP. Rulers, protractors, and compasses can be taken into the examination. Candidates who don't have English as a first language were allowed to use bilingual dictionaries until 2023; these are now no longer permitted.
A formulae booklet was available to all candidates for all examinations up to and including those in 2018. As of 2019, candidates are no longer be issued with a formulae booklet; instead they will be expected to recall, or know how to derive quickly, standard formulae. All the required standard formulae are given in an appendix to the new specification.

## Marking

STEP is marked by teams of mathematicians specially trained for the purpose. All the markers have Mathematics degrees and most are reading for PhDs at Cambridge. Each question is marked by a small team who coordinate to ensure their question is marked fairly and that all correct solutions are given appropriate marks. Markers are closely supervised by a team of marking supervisors, usually senior teachers, who are responsible for the mark scheme and by a senior Mathematics assessment expert. All non-crossed-out work is assessed and a candidate's final score is based on their six highest scoring solutions. All papers are checked at least twice to ensure that all of a candidate's non-crossed-out solutions have been assessed. A candidate's marks are then independently entered twice into a database to ensure that there are no clerical errors in mark recording. The mark data is then checked a further time by a small team who hand check a random selection of scripts.

## Scoring

There are five possible grades awarded. From best to worst, these are 'S' (Outstanding), '1', '2', '3', and 'U' (Unclassified). The rule of thumb is that four good answers (to a reasonable level of completion) will gain a grade 1; more may gain an S, and fewer will gain a correspondingly lower grade. The grade boundaries shift from year to year, and the boundaries for STEP 3 are generally lower than those for STEP 2.
All STEP questions are marked out of 20. The mark scheme for each question is designed to reward candidates who make good progress towards a solution. A candidate reaching the correct answer will receive full marks, regardless of the method used to answer the question.
All the questions that are attempted by a student and not crossed out will be assessed. However, only the six best answers will be used in the calculation of the final grade for the paper, giving a total maximum mark of 120.

## Timing and results

STEP is normally sat at a candidate's school or college. Alternatively, the test can be taken at any test centre authorised to run STEP. Entries for STEP are typically accepted from the start of March until the end of April and late entries (with late entry fees) accepted until mid-May. STEP is taken in mid-to-late June, with online results available in mid-August, issued on the same date as A Level results, typically at midnight.

## Usage

There is some variation in how institutions make use of the results – candidates can contact the relevant institution(s) for more information. However, STEP is typically taken post-interview and the results used to supplement candidates' exam results. For applicants to the University of Cambridge, candidates' scripts are made available to admissions officers. This enables officers to make judgements on the basis of candidates' actual work, rather than on just their marks or grade.

## Preparation

STEP does not require a lot of extra knowledge as they are designed to test skills and knowledge of topics within the A Level syllabus; however, preparation is advised as questions are significantly more challenging than those found in standard A Level examinations. Ideally, students should begin preparation from the summer preceding the academic year of the STEP series they intend to sit.
Practice materials, including past papers, example solutions, and a STEP formula booklet, are available for free from the Cambridge Assessment Admissions Testing website. The STEP support programme provides modules for individual additional study, along with hints and solutions. Furthermore, the book "Advanced Problems in Mathematics: Preparing for University" by Stephen Siklos, a former paper-setter for STEP, has been specifically written for students preparing for it.
