LSE Mathematics, Statistics and Data Science: TMUA Guide for 2027 Entry

The London School of Economics and Political Science (LSE) encourages applicants to its Mathematics, Statistics and Data Science undergraduate degrees to take the TMUA for 2027 entry, stating that a good score may make an application more competitive. The same policy applies across all eight courses in this group, spanning seven UCAS codes from Actuarial Science to Data Science: recommended, but not mandatory. The TMUA is run by UAT-UK and delivered at Pearson VUE test centres, with two papers of 20 multiple-choice questions each, 75 minutes per paper (150 minutes in total), reported on a 1.0 to 9.0 scale. This page covers LSE's official position, the key dates for 2027 entry (including the fixed sittings for mainland China, Hong Kong and Macau), and how to prepare with FrontierVUE's 18 past papers and 10 mock sets.

01 LSE's Official Requirements: Which Courses Involve the TMUA

LSE's Entry Requirements page for 2027 entry states one consistent policy for every course in this group: the TMUA is recommended but not mandatory. In the official wording, applicants are encouraged to take the test and a good score may make an application more competitive. The group covers eight courses under seven UCAS codes, from Actuarial Science to Data Science, all under this single policy.

N321

BSc Actuarial Science

Both routes, with and without a placement year, share this single code and the same policy: recommended, not mandatory; a good score may strengthen the application

N3UD

BSc Data Science

Recommended, not mandatory; a good score may strengthen the application

GN13

BSc Financial Mathematics and Statistics

Recommended, not mandatory; a good score may strengthen the application

G0N0

BSc Mathematics, Statistics, and Business

Recommended, not mandatory; a good score may strengthen the application

G140

BSc Mathematics with Data Science

Recommended, not mandatory; a good score may strengthen the application

G1L1

BSc Mathematics with Economics

Recommended, not mandatory; a good score may strengthen the application. Note this is a different course from GL11

GL11

BSc Mathematics and Economics

Recommended, not mandatory; a good score may strengthen the application. Note this is a different course from G1L1

Two details worth noting: G1L1 (Mathematics with Economics) and GL11 (Mathematics and Economics) are two different courses, so double-check the code on your UCAS form; and both Actuarial Science routes (with and without a placement year) share the single code N321. All statements above come from LSE's official Entry Requirements page, 2027 entry version.

02 Key Dates and Registration (Including Mainland China, Hong Kong and Macau)

For 2027 entry the TMUA has two sittings, in October and January, with registration through UAT-UK and Pearson VUE. LSE accepts either one of them; candidates in mainland China, Hong Kong and Macau sit on fixed dates rather than choosing freely across the whole window.

Registration for the October sitting closes on 28 September 2026, per LSE's TMUA guidance page. Registration goes through UAT-UK and Pearson VUE.

October test window (accepted by LSE)

12–16 Oct 2026

The window of 12 to 16 October 2026. LSE accepts either the October or the January sitting; you only need one of them.

Fixed dates for mainland China, Hong Kong and Macau (October sitting)

15–16 Oct 2026

Candidates in mainland China, Hong Kong and Macau sit the October paper on fixed dates: 15 to 16 October 2026.

Registration closes, January sitting

21 Dec 2026

Registration for the January sitting closes on 21 December 2026, per LSE's TMUA guidance page. Registration goes through UAT-UK and Pearson VUE.

January test window (accepted by LSE)

4–8 Jan 2027

The window of 4 to 8 January 2027. LSE accepts either the October or the January sitting; you only need one of them.

Fixed date for mainland China, Hong Kong and Macau (January sitting)

8 Jan 2027

Candidates in mainland China, Hong Kong and Macau sit the January paper on a fixed date: 8 January 2027.

Hard deadline Event WindowRegistration goes through UAT-UK and Pearson VUE; both registration deadlines are per LSE's TMUA guidance page. The two rows marked in gold are the hard registration cut-offs.

The key rule: LSE only considers the first attempt in each application cycle. Sitting the test again in January after an October attempt does nothing for an LSE application, so treat your chosen sitting as your only shot.

	Paper 1	Paper 2
What it assesses	Applications of mathematical knowledge	Mathematical reasoning and logic
Questions	20 multiple-choice questions	20 multiple-choice questions
Time	75 minutes	75 minutes

The test is computer-based; the two papers total 150 minutes, and results are reported on a 1.0 to 9.0 scale.

03 How to Prepare for the TMUA with FrontierVUE

FrontierVUE's TMUA bank covers 18 past papers from 2015 to 2023 (including the official specimen) plus 10 mock sets, 971 questions in total, each with a detailed explanation and a Chinese translation. The two most recent past papers are free to try. Since LSE only counts your first attempt, preparation should be right the first time. The plan we suggest has three steps.

Past papers, 2015 to 2023, incl. official specimen

Mock sets

971

Questions, each with explanation and Chinese translation

Most recent past papers, free to try

01Step 1

Know the test

Map the scope of both papers first. Paper 2's reasoning and logic content is unfamiliar to most students, so that is the part to shore up.

02Step 2

Work through past papers

Benchmark yourself on the two free recent papers, then schedule the rest with a revision plan, breaking down each paper's question types.

03Step 3

Simulate the real thing

In the final stretch, use the mock sets under timed conditions, 20 questions in 75 minutes per paper, then walk through the test-day routine once more.

The material behind each step: for step 1, the TMUA exam overview and the syllabus guide, plus the logic and proof guide for Paper 2; for step 2, TMUA past paper practice, the revision plan guide, and the Paper 1 guide and Paper 2 guide; for step 3, the time management, common mistakes and scoring guides, finishing with the test day guide .

04 Points Specific to an LSE Application

Recommended does not mean optional in practice

LSE's own wording: a good score may make an application more competitive

Given that it is not compulsory, the TMUA is one of the few quantitative signals an applicant can actively add. Our suggestion on this page: if you take it, prepare properly.

For LSE it is first attempt only, with no room to resit

LSE treats your first attempt in the cycle as final

Unlike settings where resitting can improve your standing. If you are targeting the January sitting, spend the intervening months preparing rather than using October as a trial run.

One score covers all eight courses in this LSE group

A single TMUA result supports any course you apply to within this group, with nothing to handle separately

All eight courses here (N321, N3UD, GN13, G0N0, G140, G1L1, GL11) share the same policy.

No published score threshold. LSE's 2027 entry materials state no cut-off or reference score; the TMUA is reported on a 1.0 to 9.0 scale. The official wording says only that a good score may make an application more competitive, so ignore unverified target numbers circulating online and focus on what you control: enough practice to perform at your best.

FAQ

Frequently asked questions

Is the TMUA compulsory for LSE Mathematics and Economics (GL11)?

No. LSE's official position for 2027 entry is that the TMUA is recommended but not mandatory: applicants are encouraged to take the test, and a good score may make an application more competitive. The same policy applies to the other courses in this group, including G1L1, GN13, N3UD, N321, G0N0 and G140.

Which TMUA sitting does LSE accept? Can I sit both October and January?

LSE accepts either the October 2026 or the January 2027 sitting, but only considers the first attempt in each application cycle. Resitting therefore does nothing for an LSE application: pick one sitting and prepare to perform at your best on that day.

When and how do mainland China candidates sit the TMUA for LSE?

Candidates in mainland China, Hong Kong and Macau sit on fixed dates: 15 to 16 October 2026, or 8 January 2027, with registration through UAT-UK and Pearson VUE. Registration closes on 28 September 2026 for the October sitting and 21 December 2026 for the January sitting.

What TMUA score do I need for LSE Data Science (N3UD)?

LSE has published no cut-off or reference score for 2027 entry; the TMUA is reported on a 1.0 to 9.0 scale. The official wording says only that a good score may make an application more competitive, so aim to perform at your best through thorough practice rather than chasing an unverified number.
