YOUR ULTIMATE GUIDE
The Definitive Starter Guide To The TMUA (2022)
Written by: Matt Amalfitano-Stroud
The TMUA is one of the major hurdles in between you and getting your dream place at university. This guide is the first stepping stone on your journey to beating the exam, as you will learn everything you need to know about its format, the two papers and the questions you’ll find on exam day. Let’s get started!
TMUA BASICS: EVERYTHING YOU NEED TO KNOW
The first thing we need to take a look at is everything surrounding the TMUA. Let’s go over how you register, how it’s scored, what you need to bring and much, much more.
What is the TMUA?
The Test of Mathematics for University Admission (TMUA) is a pretty self-explanatory title. But just to clarify, it’s a 150 minute long admissions test used by a variety of universities primarily for their Mathematics courses.
The key thing to understand about the TMUA is that, for the most part, it is a non-compulsory exam. Most of the universities that use the TMUA give applicant’s the opportunity to apply for their courses without submitting TMUA results. In some cases, this may be because they accept multiple admissions exams, while others simply do not make it a requirement.
However, it is highly recommended that sit the exam and aim to score highly, as, in some cases such as Durham University and Lancaster University, achieving a certain score will likely get you an offer or even a reduced offer. Other’s, such as LSE, have clearly stated in the past that the TMUA makes you a more competitive candidate.
In recent years, predicted grades have become less relevant within university admissions, meaning the TMUA is much more important to making your application stand out (although the other parts of your application will still need to be strong).
The key exception to this is the University of Cambridge, who require all applicants (excluding mature students) to sit the TMUA for their Computer Sciences course.
What is the Structure of the TMUA?
The TMUA is made up of two separate papers consisting of 20 multiple-choice questions each. You are given 75 minutes to complete each paper. The questions on each paper are fairly different to each other:
Paper 1 focuses on mathematics in its purest form. These questions are laid out simply and will see you solving the problem that is presented to you.
Paper 2 focuses more on mathematical reasoning rather than pure knowledge. Many of the questions presented will require more than just solving a problem but to logically assess a problem or another person’s work using various techniques. Mathematical knowledge will still be essential here, but the question will be less about the solution and more about the context of the question or solution given.
This table summarises the TMUA Structure:
Why is the TMUA used?
As previously stated, the TMUA is primarily used as a tool for assess applicant’s mathematic abilities, both in terms of pure maths and logical thinking.
As a non-essential exam for the most part, it can be assumed that admissions teams will look more highly upon applicants who have sat the exam and will generally be more likely to give an offer if a high TMUA score has been achieved.
Many of the courses that accept the TMUA do not require applicants to interview, meaning this exam will be their primary way of understanding your abilities as an academic. This will typically be considered alongside your personal statement, which will give them an idea of your attitude and personality.
How much does the TMUA cost?
In order to sit the TMUA, applicants will have to pay a fee of either:
TMUA UK/EU Fee
TMUA International Fee
As well as this, you will need to pay an additional fee of £35 if you wish to appeal or enquire about your results.
Cambridge Assessments Admissions Testing (CAAD) do offer a TMUA bursary scheme for applicants who meet certain financial criteria, so be sure to check if you are eligible if you are concerned about the registration fee.
How to Register for the TMUA
Registration for the TMUA begins September 1st. Those who are attending school or college will first need to talk with the exams officer. They will inform you if your place of education is registered as a testing centre. If not, you are able to register for it become one via the CAAD website (this will need to be done by September 16th). You may also apply to sit the TMUA at an alternate independent testing centre if one is available near you.
If your school/college is already registered, your exams officer will next need to register you for the TMUA. For them to do this, you must provide the following:
- Personal Details (Name, DOB, etc)
- Your UCAS Number
- The names of the course you intend to apply for
From there, the exams officer will then be able to get you register for the exam. Once complete, you will be given a candidate number which will be your proof of registration. You must not lose this number as it may be required on testing day. The deadline for registration to the TMUA is September 30th.
If you require a modified paper, you need to apply for this by September 16th and must be able to provide medical evidence proving the requirement. Any other access arrangements must be booked by September 30th, alongside the registration deadline.
When and where is the TMUA sat?
The testing date for the TMUA is October 18th in 2022. This is two weeks earlier than previous year’s testing dates of early November, meaning applicants have lost two weeks of valuable preparation time. Therefore, it is incredibly important to begin preparations as soon as possible (using TMUA.Ninja fast-tracks your progress and get you ready in time).
As previously stated, you should be able to sit the TMUA at your school or college. However, if your school isn’t registered as a TMUA testing centre or you’re not attending a school or college, you can sit the assessment at an approved test centre.
Who has to sit the TMUA?
The TMUA is accepted by 10 universities. As previously stated, the only one of these to require the TMUA is Cambridge for their Computer Sciences course. The rest of these university courses will consider (but do not require) your TMUA score alongside the rest of your application:
Key TMUA Dates
As we’ve just seen, the TMUA will be sat on October 19th in 2022, but there are various other important dates to keep in mind, so be sure to remember these:
|Applicants Deadlines 2022|
|Registration Opens||1st September 2022|
|Modified Papers Registration /Apply to Become a Testing Centre Deadlines||16th September 2022|
|Registration Closes||30th September 2022|
|Submit Your UCAS Form||15th October 2022|
|PAT Testing Date||2nd November 2022|
|PAT Results Released||11th January 2023|
But when should you start preparing? We would recommend starting six-months in advance! You can see how we suggest you use your time with our TMUA Preparation Timeline.
What do I Need for the TMUA?
The TMUA is a written assessment, meaning you will be answering everything on paper. On the day, you’re going to need take a soft (HB) pencil with you for both papers. You will be issued with a separate answer sheet for each section on which to indicate your answers.Calculators are not permitted in the TMUA, along with any other supporting materials.
However, taking a watch with you is always a good idea. Try to bring one that can show you the time in seconds, as this will allow you to have a much more accurate idea of the time you’re spending on a question.
You will also be required to bring a form of ID to the testing centre.
How Hard is the TMUA?
At first glance, the TMUA may seem like a fairly easy test. You’re given two and a half hours to answer 40 multiple choice questions, all of which are focused on mathematics. If you have effectively prepared and are confident with you mathematical abilities, then the TMUA should be more than possible to succeed in.
That’s not to say that the TMUA is easy though, as these questions will be testing you on advanced level maths. You’re going to need to be confident with maths up to A-Level difficulty (or equivalent), so some of the topics covered will be fairly new to you. Everything covered will be in your school curriculum however.
Be aware that Paper 2 may trip you up if you haven’t properly practiced it. These questions rely more on mathematical reasoning than just pure mathematics, so the logic-based questions may catch you off guard.
Can I resit the TMUA?
Students cannot attempt the test twice during the same admissions cycle. If you apply again in another admissions cycle, you must take the test again.
Some universities do accept alternate admissions tests, including the MAT and STEP, so be sure to take one of these exams if you’re unhappy with your TMUA score.
How is the TMUA scored?
In the TMUA, each question is worth one mark. Your raw marks out of 40 will be how many questions you got correct. There is no negative marking so incorrect answers will not deduct marks from your total.
For your final result, your raw marks are converted and placed into a scale from 1.0 to 9.0. These are the scores that your prospective universities will see. Below you will find the Score Conversion Tables for both papers of the TMUA, as well as the overall conversion out of 40:

How do the universities get my results?
As the TMUA is non-compulsory for most universities, your results will not be automatically sent to them. Instead, you will need to submit them yourself once you have received them on November 29th. Here is the process of doing so:
- At the end of your test, you will receive a Confidential Results Information sheet. This contains login details for you account on Metritests. This is where you will be able to access your TMUA results when they are published.
- Under the TMUA test option, you will need click “Share Results” in order to begin the process.
- You will then need to select the universities you wish to send the results to, as well as the degree. Once you have saved this option on the site, the results will be immediately available for the universities to see.
Please note that sending the results is not a requirement after you have completed the TMUA. If, for whatever reason, you decide you don’t want your chosen universities to see your results, then simply do not complete the process outlined. The rest of your application will not be affected by this.
If you’re applying to the University of Cambridge, your results will be automatically sent to the university. There is no option to withhold your results. We have a full guide about TMUA Scoring and Results that will show you what your score means and how it is used.

TMUA PAPER 1
With the basics out of the way, let’s take look at the first paper in the TMUA, which is all about pure mathematics.
Paper 1 of the TMUA is (obviously) is the first half of the TMUA. Here, you will find 20 multiple-choice questions testing your pure mathematics skills in a variety of disciplines. While the questions are relatively straight-forward format-wise, they are far from easy!
When we say that they’re straight-forward, we mean that you’re going to solving mathematical problems and not too much else.You’re goal here is to find the solution to the mathematical problem presented to you, which is what you’d typically expect from a maths exam at this level.
You can see below exactly what to expect from a page on the TMUA:
TMUA Paper 1 Example Page
Each page contains just one question, which means you’ll have plenty of space for rough work. Remember that nothing on the question paper will be marked, so you can use the space provided for any kind of calculations that you need (which we highly encourage you to make the most of).
TMUA Paper 1 Specification
Next up, it’s time to look at the exam specification for the TMUA. This is the official list of every topic that will potentially appear in theTMUA. The specification is split into two sections, Section 1 and Section 2. Section 1 covers all of the pure mathematical knowledge that you’re going to need to know when sitting the TMUA and is required for both papers.
Section 1 is further spilt into two ‘Parts’, Part 1 and Part 2. Essentially, Part 1 covers Advanced Maths while Part 2 covers Standard Maths (which feels like the wrong order!). It feels strange to begin with the advanced knowledge required for the exam, so we’ll go out of the order of the specification and begin with Part 2:

That’s a fair amount to take in, but none of this should be new to you. Remember that the TMUA deals with content knowledge up to A-Level difficulty, so everything in the specification should be covered within your school’s curriculum. Just bear in mind the order your school teaches in may mean some topics are not covered before you sit the exam in October. If this is the case, you will need skip forward a bit and teach the topic to yourself, although asking your teacher for help is always a good idea!
If you want to learn more about this part of the exam, want to try out some practice questions or are just looking for some preparation tips, be sure to check out our TMUA Paper 1 Guide.
TMUA Paper 1 Practice Questions
With all that in mind, it’s time to take a look at some TMUA Practice Questions to put your knowledge to the test:
TMUA Paper 1 Practice Question 1
Given that, in the expansion of (3x + b)7, the coefficient of x4 is the same as the coefficient of x² in (3b + x)4, find the positive constant b.
The correct answer is A.
In the first expansion, the coefficient of x4 is given by (74)34b3 = 2835b³ and in the second, the coefficient of x² is (42)(3b)2 = 54b², and equating, we see that b = 54/2835 = 2/105.
TMUA Paper 1 Practice Question 2
Find the distance between the intersection points of y = |x – 4| and y = 5 – |x – 1|.
A) There are no intersections
The correct answer is C.
Knowing that the highest point of y = 5 – |x – 1| will be at x = 1 tells you that point is at (1,5), which is above the line y = |x – 4| as it is at (1,3) there. This tells you there are two intersection points, with a quick sketch.
While this may or may not be to scale, it doesn’t matter; we can see from the sketch that there is one intersection when both are in their first half, and one in their second half, whether the apex or base of either two graphs should be closer or further apart is irrelevant. Thus, we solve 5 – (x -1) = x – 4 (gives x =5) and 5 + x – 1 = 4 – x (gives x = 0).
These points are (5,1) and (0,4) respectively and using Pythagoras’ Theorem tells us their distance is √(5 – 0)² + (1 – 4)² = √25 + 9 = √34.
TMUA Paper 1 Practice Question 3
Every day, a man decides whether to walk his dog with probability 1/3 that he does take it for a walk, independently of choices made on other days. After 4 days, what is the probability that he walked his dog at least once every 2 days?
The correct answer is B.
For the man to walk his dog “at least once every two days”, we know he never had two consecutive days which he did not walk the dog. So, representing going for a walk as W and not going as N, the possible ways he spent his 4 days are WWWW, WWWN, WWNW, WNWW, NWWW, NWNW, NWWNWNWN. These are not all equally likely as each W has 1/3 chance of appearing, and each N has a 2/3 chance. Thus, the probability that each set of 4 days occurred is 1/81, 2/81, 2/81, 2/81, 2/81, 4/81, 4/81, 4/81.
As we only want to know the probability any one of these occurred, we can sum them, to get (1+ 2 x 4 + 3 x 4)/81 = 21/81 = 7/27.
TMUA Paper 1 Practice Question 4
When is (sin2x)/(1 – cos2x)(3x -2) ≥ 0 in the range of 0 < x < π?
A) log32 ≤ x ≤ (π/2)
B) log32 < x < (π/2)
C) (π/2) < x ≤ log32
D) 0 < x < log32
E) (π/2) ≤ x ≤ log32
F) 0 < x ≤ log32
The correct answer is A.
Using trigonometric identities, cos2x = 1 – 2sin²x, sin2x = 2sinxcosx.
This means that sin2x/(1-cos2x) = cosx/sinx.
We then know the critical values of x are when cosx is equal to 0(x = nπ/2). The other part of the expression has only 1 critical value at x = log32. All that’s left to determine is whether they are positive or negative around these values.
(3x – 2) is increasing, so it must be below the x-axis before x == log32 and positive after. We only need to consider π/2 which is the only critical value in range for this problem, and both sinx and cosx are positive at x = 0, so the graph must be positive before x = π/2 and negative after. We are looking for where they have the same sign, and we know that log32 < 1(as log33 = 1) so it must be log32 ≤ x ≤ (π/2).

TMUA PAPER 2
Paper 2 of the TMUA features questions that you may not be as used to. You’re going to need to implement skills in mathematical logic to get a good score here, so let’s see what you need to know!
We’ve mention this a few times already, but it’s important to properly understand that Paper 2 of the TMUA does not feature the same style of mathematical questions as Paper 1. To properly understand why this is, let’s look at an example of a typical page in Paper 2:
TMUA Paper 2 Example Page
The difference should be apparent immediately. Questions here are not about simply solving a problem, but using the solution to answer questions within the context of the question, or to evaluate a problem and/or solution and discuss it’s reasoning or its flaws.
This makes its sound like an entirely different subject than Paper 1, but the difference isn’t as extreme as you think. These are still undeniably maths questions, and as such you will be required to use maths to solve a problem. The key thing is that you will have extra steps and extra things to consider when doing so.
Even though the question may ask you to disprove a mathematical argument or explain a problem, you’re still going to be using the core principles of mathematics that you’ve been learning throughout the years.To understand this further, lets move on to the specification for Paper 2:
TMUA Paper 2 Specification
First things first: there is no new mathematical knowledge that will be required for this paper. Everything that will be included here is covered in Section 1 of the TMUA Specification. That will certainly make your revision a bit easier, as everything you need to know for both sections is covered there; at least in terms of pure maths.
As you could probably guess, the different style of questions for Paper 2 will require some different types of skills and techniques. These have all be outlined in the specification under Section 2, so let’s take a look at what you need to practice:
TMUA Specification: Section 2
The Logic of Argument
This is a concept that definitely isn’t unique to maths but will be required for a lot of the questions you’ll encounter during your revision and on testing day. Using this in mathematics may be slightly easier than a subject like politics however, as a Mathematica problem is always going to have an objectively correct solution.
Mathematical logic, as it’s called in the context of the TMUA, will be used for fairly simple scenarios here, so it’s not going to be too complex. Essentially, this will be your method of developing a correct statement to answer the question you’ve been asked. It will typically take a form like these:
If A then B
A if B
A only if B
A if and only if B
So for example, if x is odd, then x + 1 is even. Keep in mind that you will also need to understand the converse and contrapositive of your statement.
On the other side of this, you will need to be able to analyse statements included within questions that will ask you to prove or disprove them.
Some of the key terms of revise here include necessary, sufficient, for all, for some and there exists.
All of these questions are multiple-choice, so you’re not going to need to be writing up full statements providing the proof of your findings. However, some questions will still relate to this in someway, whether it’s due to the question providing different forms of proof in its answers, or potentially asking you to disprove an argument due to missing or insubstantial proof.
There are different forms of proof that you’re going to need to consider include:
- Direct deductive proof
- Proof by cases
- Proof by contradiction
- Disproof by counter example
These are the key principles to mathematical proof highlighted by the specification:
- Deducing implications from given statements
- Rearranging statement sequences to give a correct order
- Using sophisticated chains of reasoning to solve
These will all be important techniques to practice when solving these questions.
Identifying Error in Proofs
This one is linked pretty closely to the last point, seeing as they both relate to mathematical proof. We touched on this briefly before, but some questions are going to require you to review a given sequence of statements or work in order to determine errors within them.
In the TMUA, this is referred to as identifying errors in purported proofs, as what you’re reviewing will be presented as the proof to a solution (basically the working out). Of course, there will be an error in there somewhere and your job could be one of various things.
You may be required to simply identify the mistake within the proof. However, the questions could potentially go further and ask you to determine how the error was caused in the first place, essentially finding the reasoning behind it. Of course, you may also be asked to correct the mistake and provide the actual solution to initial problem.
There are a few plenty of simple mathematical errors to keep an eye out for in purported proofs. A couple of examples given include the following statements:
If ab = ac, then b = c
If sin𝐴 = sin𝐵, then 𝐴 = 𝐵
These are pretty simple mistakes, but they may be difficult to spot within the large sequences of statements that are typically featured in Paper 2 questions.
It’s pretty difficult to properly understand the use of all these techniques without seeing them in context, as these aren’t the kind of skills you can “revise” in a traditional sense. Our TMUA Paper 2 Guide goes into more detail about how you can tackle these questions effectively. However, practice is going to be the most important thing you can do to prepare.
Outside of the TMUA, this is a very uncommon style of question which means practicing it can be tricky. You’re unfortunately not going to be able to find many questions like this outside of TMUA practice materials and past papers, as neither the STEP or MAT exam have anything that compare to Paper 2. Therefore, you need to be careful not to use up all of your resources too early into your preparation timeline.
It’s good to take past papers in proper exam conditions, but you won’t get as much out of this until you’ve effectively revised your knowledge and skills in a more casual setting. Of course, the best way to mitigate this problem is with TMUA.Ninja, which provides you with 100’s of additional practice questions and an easy to use exam simulator, including worked solutions for every question included.
TMUA Paper 2 Practice Questions
To get your practice started, let’s try out some practice questions and get a better idea of what to expect:
TMUA Paper 2 Practice Question 1
Consider the statement: “If n is an integer and n² is divisible by 4, then n is divisible by 4”.
How many counterexamples are there to this in the range 50 ≤ n ≤ 100.
The correct answer is E.
Clearly we need to count the number of multiples of two, but not of four, in the range. So 50,54,58,…,98. There are 13.
TMUA Paper 2 Practice Question 2
A Pythagorean triple is where 3 positive integers, a, b and c fit the equation a² + b² = c².
The 2 smallest integers of a Pythagorean triple are 20 and 21. Find the third integer. Comparing this to the smallest Pythagorean triple, what is the highest common factor of the sum of the integers in both equations and the integer formed by the two largest numbers plus the 2 smallest numbers from both equations.
The correct answer is A.
20² + 21² = 29²
The smallest triple is 32 + 42 = 52. If this is not known, it can easily be worked out by writing down all the square numbers until you see 2 that will add to make another one.
Sum of the integers in both equations – 20 + 21 + 29 + 3 + 4 + 5 = 82.
Product of the two largest numbers minus the 2 smallest numbers from both equations = (29 +21) + (3+4) = 57.
HCF of 57 and 82:
82 factors: 1, 2, 41, 82
57 factors: 1, 3, 19, 57
HCF = 1
TMUA Paper 2 Practice Question 3
Consider the graphs of the two functions y = mx + 10 and y = log2x. Which of the following correctly identifies the sufficiency and necessity of:
- m < 0
- m > 10
in relation to the statement that there are intersection points of the two graphs?
A) Both necessary and sufficient.
B) Both necessary.
C) Both sufficient.
D) 1 is sufficient, the other is necessary.
E) Only 1 is necessary.
F) Only 1 is sufficient.
G) Neither is necessary or sufficient.
The correct answer is F.
We want the two graphs to intersect but equating the expressions won’t get us very far. Instead, a sketch of both graphs is more illuminating. The line intersects the y-axis at 10, which is much higher than the other line. The gradient of log2x is decreasing, and as the gradient of the straight line is constant, if it begins large enough, they will never meet. 10 is one such value and so anything larger will also never meet the curve. However, there are also slightly smaller values which would also work, so it is not necessary. For m negative, the line must proceed downwards from(0,10). One can see that, as eventually log2x = 10, even an almost flat decreasing straight line would intersect the curve. Thus, no matter the value of m, if it is negative, the lines must cross. So, 1 is sufficient, 2 is neither.
TMUA Paper 2 Practice Question 4
Consider the following proof of the alternate segment theorem:
- Let a tangent touch a circle at A and let B, C be two points on the circumference of the circle. Let the angle between the line CA and the tangent b α°.
- By drawing radii from C & A to the centre of the circle, which we will call O, we know that the angle between OA and the tangent is 90°.
- This means the angle BAO is (90 – α)°.
- Since the triangle OBA is isosceles, the angle OBA is also (90 – α)°.
- Then the angle AOB is 180° – (180 – 2α)° = 2α°
- This means the angle ACB is (2α/2)° = α°.
Where is the first error?
A) The proof is correct
B) Line 1
C) Line 2
D) Line 3
E) Line 4
F) Line 5
The correct answer is C.
By drawing the circle and tangent, the error becomes relatively clear. The angle that would be equal to α using the alternate segment theorem would be ABC, not ACB as is calculated in the question, so the result is clearly false. To find the error, notice that angle BAO has nothing to do with α, and it is in fact angle CAO that is(90 – α)º. So, the error is on line III.
These practice questions should highlight how different these questions can be to what you’re used to, but should also show you the similarities and ease your concerns about them. Remember; it’s still maths, it’s just presented a bit differently and requires a slightly different viewpoint. As long as your maths knowledge is on point, you shouldn’t face any major problems (you still need to practice, of course!)
