Section 04
Imperial Mathematics and Computer Science requires the Test of Mathematics for University Admission (TMUA) for 2027 entry. The test is run by UAT-UK and delivered through Pearson VUE test centres.
TMUA has two fixed papers: Paper 1, Applications of Mathematical Knowledge, and Paper 2, Mathematical Reasoning. October 2026 testing runs from 12–16 October 2026, and January 2027 testing runs from 4–8 January 2027.
Account creation, access-arrangement applications and bursary applications open on 1 June 2026 at 15:00 BST. October booking closes on 28 September 2026 at 18:00 UK time, while January booking closes on 21 December 2026 at 18:00 GMT. October results are released on 16 November 2026, and January results are released on 8 February 2027.
The TMUA matters because it gives Imperial another way to compare applicants taking different qualifications and school routes. Imperial and UCAS do not publish a simple GG14 score threshold in the checked sources. A strong approach is to prepare with timed, calculator-free mathematical reasoning and reviewing errors carefully rather than trying to guess a hidden cut-off.
For applicants in China, Hong Kong and Macau, UAT-UK limits TMUA to 15–16 October 2026 or 8 January 2027. International applicants should book early because test-centre availability and access-arrangement review can affect the practical timeline.

Question Types You’ll See
Imperial Mathematics and Computer Science interviews typically run 20–30 minutes. The interview tests both mathematical reasoning and computational thinking. You may receive separate sessions or a combined session covering mathematical problem-solving and algorithmic or logical questions.
Mathematical content mirrors the Mathematics interviews: problem-solving in algebra, calculus, proof and combinatorics. The computing component may include questions about algorithms, data structures, complexity or logical reasoning. Interviewers want to see that you think clearly across both disciplines and can reason precisely under guidance.
Prepare by working through STEP past papers and UKMT Olympiad problems for the mathematics side, and by practising algorithmic problem-solving on platforms such as Project Euler or Advent of Code for the computing side. Reading a short introduction to discrete mathematics or combinatorics that is not in your A-level syllabus gives you material to engage with at interview.

Section 06
For 2027 entry, Imperial Mathematics and Computer Science as a high-academic-threshold, TMUA-informed selection process. The published A-level requirement includes A* in Mathematics and A* in Further Mathematics, and the IB requirement includes 41 points overall with 7 in HL Mathematics and 7 in another relevant HL subject.
If an interview or discussion is used, you should be ready to explain mathematical and computational reasoning aloud, but this should not be presented as a fixed official stage.
Our recommendation · weighting of admission factors
Oxbridge Mentors recommendation, drawn from observed offer patterns. Imperial College London does not publish official weightings — exact balance varies by college, course and year.
Section 07
A good JMC personal statement should make the link between mathematics and computing explicit. A strong approach is to choose 2 or 3 examples where an abstract idea led to a computational method, or where code helped you test a mathematical claim.
Do not write a generic computer science statement with a mathematics sentence added at the end. It is better to discuss one algorithm, proof, simulation or modelling project in detail than to list ten topics without reflection.
Because the course requires TMUA and high mathematical preparation, your statement should support the same profile: problem solving, proof, abstraction and implementation. It helps to show what went wrong in a project or problem set, because that reveals how you think under pressure.
See a full annotated example with line-by-line expert commentary.
Mathematics and Computer Science PS Example →Section 08
Projects work best when they show both sides of the degree. A strong project does not need to be large, but it should have a mathematical question, an implementation choice and a short evaluation of the result.
Useful project directions include:
Section 08
Other supercurriculars should deepen your mathematical reasoning and computational fluency. A strong approach is to choose activities that produce evidence you can explain clearly, such as a proof, a program, an error log or a short written exposition.
These are support, not substitute. A polished list of activities will not compensate for weak mathematical preparation.
Proof-writing practice:
Work through proof-based problems beyond A level, focusing on clarity, definitions, counterexamples, induction and contradiction.
Algorithms and data structures:
Implement core data structures and analyse their complexity rather than only using library functions.
Mathematical modelling in code:
Turn a mathematical model into a program, test assumptions and explain how the mathematics shapes the implementation.
Reading and exposition:
Read a challenging mathematics or computing text and write a concise explanation of one theorem, algorithm or idea in your own words.
Timed problem solving:
Use UKMT BMO STEP-style and informatics problems to practise accurate reasoning under time pressure.
Personal software projects:
Build a small but finished project that shows algorithmic thinking, testing, version control and reflection on trade-offs.
Section 08
Competitions are not required, but they can stretch the same skills that matter for this course: proof, logic, algorithms, accuracy and reasoning under time pressure.
None are required; one or two done well beats five half-attempted.
Section 09
Year
01 / 03
1
Programming, algorithms and core university mathematics
Indicative first-year structure: core foundations across programming, algorithms, logic, analysis, calculus and linear algebra, with practical computing work alongside formal mathematical reasoning.
Year
02 / 03
2
Software engineering, operating systems, probability and mathematical options
Indicative second-year structure: more specialised computing and mathematics, with core computing/statistics content and option groups that can lean toward theoretical computer science, systems, numerical analysis, algebra, statistics or project-based work.
Year
03 / 03
3
Advanced computing, mathematical depth and group project experience
Indicative final-year structure: higher-level options and substantial project-style work, allowing students to demonstrate technical independence and applied problem-solving.
Section 10
Proof-focused books matter for JMC because Imperial is not looking only for programming enthusiasm: you need to show that you can handle definitions, induction, recurrence relations, asymptotic reasoning and complete arguments. Start with How to Think Like a Mathematician Concrete Mathematics Introduction to Algorithms The Algorithm Design Manual And Mathematics: A Very Short Introduction.
Visual and lecture-based resources are most useful when they help you revisit a hard idea, not when they replace problem solving. Use 3Blue1Brown Computerphile Numberphile MIT OpenCourseWare And CS50 For second explanations of linear algebra, algorithms, discrete structures or computing theory.
Podcasts are best treated as prompts for follow-up reading rather than as evidence of technical depth.
Structured courses are useful when they produce worked exercises, code, proofs or corrections you can point to later. Use Mathematics for Computer Science Introduction to Algorithms CS50x A-level Mathematics for Year 12 - Course 1 and A-level Further Mathematics for Year 12 - Course 1. Keeping notes on solved problems, failed attempts and corrections gives you material for the personal statement and for any academic discussion.
Section 11
Discover Uni's broader data points to IT, business/research/administrative and finance professional roles as major published occupation groups, while the GG14 page warns that displayed data comes from this and other courses.
Section 12
Imperial/UCAS describes contextual admissions as a holistic process that considers barriers and wider context alongside the application, relevant test results and other evidence. This does not remove the course's published academic bar, which remains A*A*A at A level with A* in Mathematics and A* in Further Mathematics, or 41 IB points with 7 in HL Mathematics and 7 in another relevant HL subject.
If your school does not offer Further Mathematics or an equivalent advanced mathematics route, make sure that context is clearly explained through the UCAS reference or other allowed application context. You will still need evidence of advanced mathematical readiness, so it helps to build a clear record of problem-solving, proof and TMUA preparation.
English-language evidence applies to applicants who need to demonstrate proficiency, and the verified current course level is IELTS Academic 7.0 overall with 6.5 in each element or accepted equivalents.
