Please note that the ENGAA will be sat on October 19th in 2022.

This date is different from previous years of the ENGAA, which was traditionally sat in early November. 

Please be aware of this change and plan your preparation accordingly. If you’re looking for a preparation platform that fast-tracks your revision, check out ENGAA.Ninja today!

What is the ENGAA?

If you’ve not come across the ENGAA structure before, here’s a quick recap:

ENGAA Test Format

The ENGAA is sat by applicants of Engineering at the University of Cambridge on October 19th 2022, which is around two weeks earlier than in previous years.

The ENGAA consists of two papers sat back-to-back, Section 1 and 2. Each paper is made up of multiple-choice questions that cover topics from mathematics and physics at both a basic and advanced level

Section 1 is split into two parts that cover both basic and advances maths and physics, with 20 questions to answer for each

Section 2 consist of just one part, with just 20 questions on the paper. All of these questions will revolve around Advanced Physics. It’s not just a simple repeat of Section 1B however, so we’d recommend you check out our ENGAA Section 2 Guide to find out more about what you’ll be doing in the second half of the exam.

You’ll have one hour to complete each section, making the exam last two hours in total. Remember, you won’t be allowed a calculator or any other form of supporting material for any of the sections of the exam.  

How is the ENGAA Scored?

The ENGAA is scored based on the amount of correct answers you get, there is no penalty for incorrect answers. Each Section will be scored separately on a scale of 1.0 – 9.0, with Section 1 receiving one score for each of the two parts you complete. 

Below you can see the Distribution of Scores for applicants in the 2021 exam cycle

ENGAA Section 1A Score Distribution 2021

ENGAA Section 1B Score Distribution 2021

ENGAA Section 2 Score Distribution 2021

You can see there’s a clear trend in each Section as to what the most common score is, which can be used to assess the difficulty of each part of the exam. For example, it’s clear that Section 2 is the more difficult of the two papers, with applicants generally scoring less compared to both parts of Section 1.

You can find more information about the full ENGAA in our Definitive Guide.  

There’s no better time to start your ENGAA preparation than now! 

Utilise over 900 exam quality questions, each with comprehensive solutions to help you always learn the correct answer. We make sure that the difficulty of the questions matches that of the real exam. Always practice for the real thing. So, why not start for free?


Now let’s have a look at Section 1 is laid out, and what we need to know for Section 1A specifically. 

Exams Ninja Paper 1A Icon

The ENGAA is designed for students who are currently in the process of completing their Maths and Physics A-Levels.

What does this mean?

It means that you are expected to have an excellent knowledge of GCSE Maths and Physics and a good standard of knowledge in A-levels Maths and Physics too. 

Section 1A is made up of 20 multiple choice maths and physics questions. 1B follows up with Advanced Maths and Physics questions. You have 60 minutes for Section 1 and since Section 1 is split between 1A and 1B, you have approx. 30 minutes per part and 90 seconds per question.

Here’s a standard example of what a page from the Section 1 paper will look like: 

ENGAA Section 1A Example Page

Each page of the question book will contain one or two questions depending on their size. Pages should provide you with enough empty space to write down your working out, which you will need to do as no extra paper is provided for rough work, nor is rough work allowed on your answer sheet.

We have a complete guide on the ENGAA which covers literally everything if you are looking to learn about the other sections too!

What Does Section 1A Require?

As mentioned above, applicants should have expert knowledge in GCSE Maths and Physics and a good grasp of A-Level Maths and Physics. Overall, the ENGAA is a tough exam. You may do well if you are amazing in Maths and Physics but the time constraints make the exam even more difficult.

In order to explain what is required, here is the syllabus for both Maths and Physics outlined below:

What can you do to improve your preparations for the ENGAA and increase your chances of getting that dream offer? Let’s find out!

Exams Ninja ENGAA Thumbs up Engineering Icon

In order to score highly in Section 1A, here are some points to consider.  

Firstly, and most importantly, past papers are crucial. Completing these in exam conditions is the best practice. This will also give you a realistic idea of what the exam will be like. You can learn more about how to create a preparation plan, including past papers, with our ENGAA 6-Month Preparation Timeline.

Exams.Ninja Tip 

With many Oxbridge admissions tests, the older past papers tend to be easier, so working from the older papers to the new ones is a good idea. This will allow you to turn the notch up on the intensity, whilst also sharpening your skills on familiar questions.


Use elimination

In Section 1A, you will find there are 5 potential answers to the question, whereas in Section 1B there are 8. Therefore, using the process of elimination is a lot easier than later on in the paper.

Most ENGAA questions will require 2-step calculations. Here is an example:

A metal ball is released from the roof a 20-meter building. Assuming air resistance equals is negligible; calculate the velocity at which the ball hits the ground. [g = 10ms-2 ]

  1. 5 ms-1
  2. 10 ms-1
  3. 15 ms-1
  4. 20 ms-1
  5. 25 ms-1

When the ball hits the ground, all of its gravitational potential energy has been converted to kinetic energy. Thus, Ep = Ek:

Exams.Ninja Tip 

  • Remember that to get the correct answer, you must always work in SI units i.e. do your calculations in terms of meters (not centimetres) and kilograms (not grams), etc.

  • Knowing SI units is extremely useful because they allow you to ‘work out’ equations if you ever forget them e.g. the units for density are kg/m3. Since kg is the SI unit for mass, and m3 is represented by volume –the equation for density must be = Mass/Volume. This can also work the other way, for example, we know that the unit for Pressure is Pascal (Pa). But based on the fact that Pressure = Force/Area, a Pascal must be equivalent to N/m2.



Due to the difficulty of Section 1A as well as its time-constrained nature, it would be a good idea to clear up what formulas you need to know before diving into your revision.

All of the formulas you’ll see below are going to be needed for the physics section of your exam. 

Even if questions relating to some of these formulas don’t appear in the paper, you will still need to understand them in order to succeed in your studies as they will come up frequently.  

Essential Maths Formulas

Core Geometric Formulas

ENGAA Core Geometric Formulas

Quadratic Formula

The solutions for a quadratic equation in the form ax² + bx + c = 0 are given by: x = (-b±√(b² – 4ac))/(2a).

Remember, you can use the discriminant to determine how many solutions a quadratic equation has:

b² − 4ac < 0 ⇒ No solutions

b² − 4ac = 0 ⇒ 1 repeated solution

b² − 4ac > 0 ⇒ 2 distinct solutions

Completing the Square

When a quadratic equation can’t be factorised easily and is formatted as ax² + bx + c = 0, then you can rearrange it into the form a(x + b/2a)²[c b²4a] = 0

In the ENGAA, it’s unlikely that you’ll get a quadratic equation where a > 1 or an equation that doesn’t have easy factors. This gives you an easier equation: (x + b/2)² + [c b²/4] = 0. Here’s an example:

Consider: x² + 6x + 10 = 0.

We can’t factorise this equation easily but we can note that: x² + 6x − 10 =(x + 3)² − 19 = 0.

Therefore, x = −3 ± √19. 

Difference Between Two Squares

If you have to simplify expressions but find that there aren’t any common factors, but the expression does have square numbers, you will sometimes be able to factorise it by finding the difference between the two square:

x² − 25 can also be expressed as (x + 5)(x – 5).

Maths Practice Question 3

 S, T, U and V are points on the circumference of a circle, as shown in the diagram, and O is the centre of the circle.  

Given that angle SVU = 89°, calculate the size of the smaller angle SOU.

A) 89°






The correct answer is E

This question tests your knowledge of circle theorems. Angles SVU and STU are opposites and add up to 180° – therefore, STU = 91°.

 The angle of the centre of a circle is twice the angle at the circumference – therefore, SOU = 2 x 91° = 182°.

Maths Practice Question 4

An unbiased coin is flipped 4 times. What is the probability of obtaining 2 heads and 2 tails?

A) 1/16

B) 3/16

C) 3/8

D) 9/16

E) None of the above

The correct answer is C

To approach this question, list the six ways of achieving this outcome: HHTT, HTHT, HTTH, TTHH, THTH and THHT. The probability of each of these six outcomes is given by:

1/2 X 1/2 X 1/2 X 1/2 = (1/2)4   = 1/2  

Therefore, the probability of two heads and two tails is: 

P= 6X  1/2= 6/16 = 3/8.

Physics Practice Question 1

A battery with an internal resistance of 0.8 Ω and e.m.f of 36 V is used to power a drill with resistance 1 Ω. What is the current in the circuit when the drill is connected to the power supply?

A) 5 A

B)10 A

C) 15 A

D)20 A

E) 25 A

F) 30 A

The correct answer is D.

The total resistance = R + r = 0.8 + 1 = 1.8 Ω and I = e.m.f / total resistance = 36/1.8 = 20A

Physics Practice Question 2

Which of the following statements are correct?

1. Electromagnetic induction occurs when a wire moves relative to a magnet.

2. Electromagnetic induction occurs when a magnetic field changes.

3. An electrical current is generated when a coil rotates in a magnetic field.

A) Only 1

B) Only 2

C) Only 3

D) 1 and 2

E) 2 and 3

F) 1 and 3

G) 1, 2 and 3

The correct answer is G.

Electromagnetic induction is defined by statements 1 and 2. An electrical current is generated when a coil moves in a magnetic field.

Physics Practice Question 3

Which of the following statements is true?

A) When an object is in equilibrium with its surroundings, there is no energy transferred to or from the object and so its temperature remains constant.

B) When an object is in equilibrium with its surroundings, it radiates and absorbs energy at the same rate and so its temperature remains constant.

C) Radiation is faster than convection but slower than conduction.

D) Radiation is faster than conduction but slower than convection.

E) None of the above

The correct answer is B.

When an object is in equilibrium with its surroundings, it radiates and absorbs energy at the same rate and so its temperature remains constant meaning. there is no net energy transfer. Radiation is slower than conduction and convection.

Physics Practice Question 4

The graphs below show current vs. voltage plots for 4 different electrical components.

Which of the following graphs represents a resistor at constant temperature, and which a filament lamp?

ENGAA Physics 1A Q4 Fixed Resistor and Filament Lamp Table

The correct answer is A

For a fixed resistor, the current is directly proportional to the potential difference. For a filament lamp, the metal filament becomes hotter as the current increases. This causes the metal atoms to vibrate and move more, resulting in more collisions with the flow of electrons. This makes it harder for the electrons to move through the lamp and results in increased resistance. Therefore, the graph’s gradient decreases as current increases.
