ENGAA GUIDE

ENGAA Section 1B: Your Guide to Advanced Mathematics and Physics

Written by: Matt Amalfitano-Stroud

The ENGAA is a massive part of your Cambridge Engineering application, so you need to make sure you’re confident when you enter that examination. It’s split into two sections, Sections 1 & 2, and Section 1 is split further into Sections 1A and 1B. Section 1B is all about advanced mathematics and physics, so let’s take a look at what you need to know and how you can optimise your revision! 

BASICS OF THE ENGAA

First things first, let’s go over the key information you need to know about the ENGAA.

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? 

The Engineering Admissions Assessment (ENGAA) is extremely self-explanatory. You’ll be taking this assessment during your application for Engineering and Chemical Engineering at the University of Cambridge. The ENGAA is a pre-interview assessment and in 2022, it will be sat on October 19th, a few weeks earlier than previous years. Thankfully, there is no fee required for taking the ENGAA.

The ENGAA is split into 2 main sections, Section 1 and Section 2. Section 1 is split into two more parts, Section 1A and Section 1B. Throughout Section 1, you’ll be answering a total of 40 questions based on mathematics and physics (20 for each sub-section). 

Section 1A covers your core topics in maths and physics and is typically stuff that you should know from GCSE and early A-Levels.

Section 1B takes things further by looking at Advanced Mathematics and Physics. These 20 questions will be a lot tougher and will require more in-depth knowledge of maths and physics, although it will still be covering topics that you should be familiar with. This section doesn’t focus so much on testing completely different skills than Section 1A, but rather expands on what has already been covered.  

Section 2 doubles down on Advanced Physics, with 20 more multiple-choice questions to complete in 60 minutes. These questions will be tough, so make sure you’re prepared for them! If you’re not sure where to start, we would recommend our ENGAA Section 2 Guide!

Here’s a quick summary of the test format: 

ENGAA Test Format

How is the ENGAA Scored? 

The scoring in the ENGAA is fairly simple. Each section (including each part of Section 1) is scored on a scale between 1.0 (low) and 9.0 (high) which is converted from your raw marks based on your correct answers. Here are the Score Distributions for the ENGAA in the 2021 admissions cycle.

ENGAA Section 1A Score Distribution (2021)

ENGAA Section 1B Score Distribution (2021)

ENGAA Section 2 Score Distribution (2021)

You can see from these charts that the average scores didn’t change too much throughout each section, with the exception of Section 1B which had an abnormal amount of applicants score a 9.0 (perhaps they used our ENGAA Preparation Platform!). In fact, every section of the exam saw a small spike of students scoring full marks, so it’s possible to ace the paper if you put the work in beforehand!

There’s a pretty clear trend in each Section that will show you the kind of score you should be aiming to reach for a successful application. Generally, you’ll be wanting to score higher than the most common scores, so aiming for at least a 4.5 will increase your chances of getting an offer. 

There’s a lot more to learn about the ENGAA, so check out our Definitive ENGAA Guide.

WHAT TO EXPECT FROM THE ENGAA SECTION 1B

The ENGAA isn’t the most complex exam in the world, at least not in terms of its format and layout. Still, it’s sensible to be familiar with how the assessment looks and works, so let’s check it out!

Exams Ninja Paper 1B Icon

The ENGAA isn’t anything mind-blowing when it comes to how it’s presented, but that just means it’s nice and simple, allowing you to focus on answering the questions.

Sections 1A and 1B are laid out pretty much identically, barring the content within the questions. Each sub-section, referred to as “Part A” and “Part B” in the paper, is labelled and separated from each other, so if you’re unsure which part you’re currently on, just look for the title page. Keep in mind that the ENGAA is split between two papers, so Section 2 won’t be on the paper that you’re initially given. 

Exams.Ninja Tip 

The questions in Section 1 are numbered from 1 – 40, meaning there is no split in numbering between Part A and Part B. Therefore, another way of checking which part you’re on is checking the question number, if you’re on question 21 or above, you’re in Part B!  

 
 
 
 
 
 
 
 

Each page will contain one or two questions depending on their length and amount of answer options. Speaking of which, each question will have a maximum of eight answers to choose from, all of which are labelled from A – H. 

Here’s what a typical page will look like in the ENGAA: 

ENGAA Section 1B Example Page

The amount of free space you get will depend on the size of the question, but you’ll need to make sure you make the most of what is given, as you will not be allowed additional paper for working out. Your answer sheet, which is separate from the questions, will be reserved for final answers only, no rough work is permitted on it. 

ESSENTIAL INFORMATION FOR ENGAA SECTION 1B

There’s a lot to revise when it comes to the ENGAA, especially for the advanced questions. This is a rundown of the essential bits to revise before you take the exam. 

Exams Ninja ENGAA Knowledge Icon

First of all, let’s take a look at the official specification for the ENGAA. The specification provides an outline for all the knowledge applicants are expected to have when taking the assessment. We’ve already looked at the specification for the basic mathematics and physics needed for Section 1A in our ENGAA Section 1A Guide, so let’s jump straight into Advanced Mathematics!

Algebra and Functions

Algebra is used in all sorts of mathematics, so this is one that you really need to understand. Some of the things you’ll be expected to know are:

Sequence and Series

Sequence and series are all about recognising, identifying and progressing numerical patterns, so you should hopefully be able to recognise a question about it when you’re sitting the ENGAA! Some of the areas covered in the exam include:

Two-Dimensional Coordinate Geometry

Geometry is the mathematics of shapes, so you’ll need to perfect your skills with graphs, angles and converting equations. You’ll need to brush up on the following:

Trigonometry

The triangular offshoot of geometry, there are plenty of unique rules at play that you’ll need to revise, including:

Exponentials and Logarithms

Exponents and their inverse, logarithms, will be covered in the ENGAA, so you’ll want to revise the following:

Differentiation

The ENGAA will require you to find derivatives and answer questions based on them, so you’ll need to revise the following: 

Integration

Integration is very interlinked with geometry, so you’ll need to make sure you have the following knowledge prepared for the exam: 

Graphs of Functions

Graphic interpretations of functions are extremely handy in mathematics, but learning to use and create them is pretty difficult. You’ll want to revise your knowledge on the following:

That’s a lot of maths to remember! However, that’s only half of it, as we’ve now got Advanced Physics to go through. Let’s take a look!

Forces and Equilibrium

These are the basis of all physics and super important to revise! Topics to look at include: 

Kinematics

This one is a classical branch of mechanics involving the calculation of possible motion without regard to related forces. It goes hand-in-hand with mathematics, so there are a lot of techniques and equations you’re going to need to remember, including:

Newton’s Laws

Newton’s laws of motion are 3 essential rules that will apply to any kind of mechanical science that you use. They are as follows:

  1. An object will not change motion unless a force acts on it.
  2. The force of an object is equal to its mass multiplied by its acceleration.
  3. When two objects interact, they apply forces to each other in opposite directions and of equal magnitude. 

You’re going to need to be able to use these rules in a variety of ways, including:

Momentum

Another major area of physics, you’ll want to begin by understanding the equation of p = mv. For the ENGAA specifically, you’ll need to revise the following:

Energy

This topic is going to require a lot of effort (or energy) to revise, so be sure to revise the following topics:

Materials

Material physics covers literally all physical matter, but you’re not going to have to know everything thankfully! However, you will need to revise the following: 

Waves

In physics, waves are defined as a disturbance that travels through space-time alongside a transfer of energy. For questions based on this topic, you’ll want to revise these topics: 

Electricity

This is an area you definitely will be seeing in Section 1A, but advanced physics will test your knowledge even further. Here are the topics you keep an eye out for: 

So that covers all the specific topics that you’ll need to revise! To wind down a little bit, let’s quickly run down something a little more basic!

Many questions will be using scientific quantities and units (SI-units) which you’re going to need to recognise. Makes sure you memorise these SI-prefixes before you enter the exam:

SI-Prefixes/Units

nano- 10–9

micro- 10–6 

milli- 10–3 

centi- 10–2 

deci- 10–1 

kilo- 103 

mega- 106 

giga- 109

These units will be used throughout the entire exam, so make sure you’re using them! For example, your calculations should be done in kilograms rather than grams.

REVISION AND EXAM TIPS FOR ENGAA SECTION 1B

With all the required knowledge out of the way, let’s spend some time looking at a few tips and tricks to help you revise and sit the ENGAA like a pro!

ENGAA Revision Tips

You now know what you need to revise, but what’s the best way to go about it? Here are a few handy tips to get you through Section 1B and beyond!

1. Plan Before You Revise

Any successful engineering student will tell you that creating a revision plan is essential for utilising your preparation time. You’ve got two full subjects to revise and they each cover pretty different topics. While maths is certainly a vital part of physics, your knowledge of trigonometry isn’t too likely to help you with a question on electric circuits. You need to prepare for everything in the ENGAA syllabus, and that’s no easy feat.  

The key to a preparation plan is the schedule, perhaps even planning 6 months in advance. Having times and dates dedicated to each subject and topic will help to keep your revision focussed. Then there’s the matter of how to spread your time across all these different topics, which is really down to your personal needs. We all have weaknesses, so focussing on improving your weaker subjects is a smart idea. For example, you could know pretty everything possible about advanced electricity, but always get caught out with waves. Which one do you think you should spend more time revising? That’s not to say that you should ignore your better topics, you need to maintain your knowledge from all topics, even your best ones.

Of course, you’re not going to be able to work non-stop, and having scheduled downtime will help you avoid procrastinating. Whether you want to set strict times for your breaks or treat them as a reward for accomplishing certain goals, you’ll need to take some time away from your work to refresh and let your revision sink in.  

 

2. Practice Without a Calculator

Remember, you’re not allowed a calculator during any part of the exam! This should be something you’re used to by now, but it’s easy to get used to the convenience of calculators when you have access to them. 

Your preparation time is your chance to break this cycle and get used to solving problems by hand. Sometimes using a calculator is inevitable, but that won’t be the case in the ENGAA. So whenever you get a chance to solve a problem by hand, put that calculator away! You’ll be thankful when you’re breezing through the ENGAA’s questions!

 

3. Complete Practice Questions and Papers

Once you feel confident in your knowledge of the ENGAA’s topics, your next step is to put that knowledge to the test. Of course, practice questions and mock papers are the best way to test yourself without the pressure or consequences of the actual exam.

To get the most of your practice time, you should seek out questions with worked solutions. With these, you’ll be able to fully understand how the question should be worked out. 

Mock exams may feel stressful and unnecessary at first, almost as if you’re forcing yourself to take the exam extra times! But once you’ve gotten through that stress the first time, the exam won’t feel as bad as you’ll have some experience of what to expect.

If you’re looking for a reliable and large collection of practice questions and papers, Exams.Ninja’s ENGAA Preparation Platform is definitely what you want! We have over 900 questions to attempt, so you won’t be running out of practice resources any time soon! 

 

ENGAA Exam Tips

It’s the big day, and you’ve got the dreaded ENGAA paper in front of you. What do you do? Here are a few tricks to help you avoid freezing in your seat!

1. Skip Ahead

Don’t be afraid to skip a question when you need to! Sometimes you’ll find yourself on a question that you just don’t get or can’t quite figure out. That’s alright, but there’s no point spending the whole of the exam trying to get it right. After all, you may be able to answer every question after it and have time to spare. 

That’s not to say you should skip the question entirely of course. While it’s not worth sacrificing the rest of your marks in the paper to get that question right, it’s still worth attempting it if you have time. And if you don’t have time, you should always try to put an answer down, even if it’s a guess! The ENGAA doesn’t have penalties for incorrect answers so you should always try to answer every question! 

 

2. Work Backwards

Remember, all the questions are going to be multiple choice, so you’re always going to have a hint of what your answer should look like when you’re solving it. If you’re not sure where to start, one option is to work backwards with each potential answer and see which answers are definitely incorrect. 

By using the process of elimination, you can easily narrow down your options or find the correct answer. If you believe you have found the correct answer, it’s always worth solving the question normally to double-check that you’ve got it right. 

 

3. Use your Space Wisely

As we’ve mentioned already, your space for working out is limited to what’s available on the question paper. In some cases, this isn’t a lot to work with, so you need to be careful to make the most of what you’ve got. 

Your working out isn’t going to be perfect, so there are going to be mistakes taking up precious space. The key isn’t to avoid these mistakes, as they can be super helpful to your method, but you should try to write as small as possible to utilise your space the most efficiently. 

For questions with graphs or shapes, use them! While these images aren’t going to be to scale, they are super handy for helping illustrate your solutions for yourself. And remember, it doesn’t matter what you write on the question paper as none of that will be marked. The only thing the examiners are going to see is your answer sheet, so don’t be afraid of making silly mistakes in your rough work!

ENGAA SECTION 1B PRACTICE QUESTIONS

You should hopefully know by now that practising actual questions is the best way to let your revision sink while preparing your exam technique. Here’s a taste of what you can expect from the ENGAA’s questions.

Exams Ninja Multiple-Choice Questions Icon

ENGAA Advanced Maths Question 1

The variable x is proportional to y cubed; y is proportional to the square root of z. 

If z doubles, x changes by a factor of:

A) √2

B) 2

C) 2√2

D) 3√4

E) 4

 

The correct answer is C.

The two relationships given are: x ∝ y3, y ∝ √z. Therefore, the relationship between x and z is given by:

x ∝ √z3

Therefore, if z is doubled, then: √23 = 2√2.

ENGAA Advanced Maths Question 2

What is the range where x2 < 1/x?

A) x < 0

B) 0 <  x < 1

C) x > 0

D) x >_ 1

E) None.

 

The correct answer is B.

ENGAA Advanced Maths Question 2 Graph

The two graphs have been sketched above. Clearly, the two graphs intersect when x2 = 1/x which is at x = 1. Now we can consider the inequality.

When x > 1, x2 > 1, 1/> 1.

When x < 1, x2 < 1, 1/> 1.

In the x < 0 range, the  1/x graph is negative. Therefore, this region does not satisfy the inequality. Thus, the range is 0 < x < 1.

 

Check out the ENGAA Graphs of Functions Syllabus.

ENGAA Advanced Maths Question 3

Which of the following has the largest value for 0 < x < 1?

A) log8(x)

B) log10(x)

C) sin(x)

D) x2

E) ex

 

The correct answer is E.

Firstly, we can approximate the values provided and then compare them with one another:

⇒ log8(x) and log10(x) < 0

⇒ sin(x) ≤ 1

x2 < 1

⇒ 1 < ex< 2.72.

Therefore, ex is the largest over this range.

ENGAA Advanced Maths Question 4

The volume of a sphere is equal to its projected area. What is its radius?

A) 3/4

B) 2/3

C) 1/2

D) 4/3

E) 3/2

 

The correct answer is A. 

The expressions for the volume of the sphere and its projected area, a circle, are equal:

(4/3) πr3 = πr2 ⇒ (4/3)r = 1.

∴ r = 3/4.

 

Check out the ENGAA Geometry Syllabus.

ENGAA Advanced Physics Question 1

What would happen to Vout if the light intensity upon the circuit below is increased?

A) Go up

B) Go down

C) Stay the same

D) Decrease to zero 

E) Increase indefinitely 

 

The correct answer is A.

As the light intensity increases, the resistance of the LDR will decrease. As the potential difference is proportional to the resistance, according to Ohm’s Law, this will increase the share of the potential across the normal resistor. Therefore, Vout will ultimately increase.

 

Check out the ENGAA Electricity Syllabus.

ENGAA Advanced Physics Question 2

 A ball is swung in a vertical circle from a string, of negligible mass, as shown in the diagram. 

What is the minimum speed at the top of the arc for it to continue in a circular path? You may use the formula av2/r , where a is the acceleration of a body undergoing circular motion with velocity v and radius r. The acceleration is directed towards the centre of the circle.

A) 0

B) mgr

C) 2r2

D) mg

E) √gr

 

The correct answer is E.

The forces acting on the ball are weight, which is constant and equal to the mass times the gravitational acceleration, and tension T which varies with position. By substituting the expression for acceleration given into Newton’s Second Law, we obtain:

Fmaa = v2/r

T + mg m(v2/r)

The minimum speed at the top of the arc is when it just manages to reach the top, which is when the tension is completely provided by the weight. Therefore, the force keeping the object moving in the circle is instantaneously its weight. Therefore:

= 0 ⇒ mg = m(v2/r) ⇒ v = √gr.

 

Check out the ENGAA Momentum Syllabus.

ENGAA Advanced Physics Question 3

The mechanism below is used to weigh two ridged uniform blocks of dimensions 2 metres by 1 metre, and mass 20 kg, on a lever connected to a weighing scale by a cable. What will the reading on the scale be?

A) 35kg

B) 40kg

C) 70kg

D) 80kg

E) 90kg

 

The correct answer is C. 

The centre of the mass of the two blocks will be at their geometric centres. So, in this case, that is halfway across each rectangle. The moments can be taken about the black point indicated on the diagram, where the weight of the blocks are used:

1 × F = (1 × (20 × 10)) + (2.5 × (20 × 10)) = 700 N.

This corresponds to a mass of 70 kg and so this will be shown on the scale.

 

Check out the ENGAA Forces and Equilibrium Syllabus.

ENGAA Advanced Physics Question 4

For the arrangement of springs below, what is the spring constant of the whole system, assuming each spring has spring constant k?

A) k/2

B) k

C) 2k2

D) 3k/2

E) 2k√3

 

The correct answer is D.

Springs behave like capacitors in series or parallel (the opposite of resistors), so we find the effective spring constant of the springs in series to be: 1/k + 1/kk2/2kk/2.

Then, we can add the constant of the parallel spring to obtain 3k/2.

 

Check out the ENGAA Materials Syllabus.

So, with all this knowledge of Section 1B of the ENGAA, you should now have a better understanding of what you’ll need to do in the exam come October!

This is all advanced stuff, so there’s going to be a lot of complex questions in the exam, some of which may trip you up. But that’s OK! At the end of the day, you’re not perfect and the examiners aren’t expecting you to be. With the knowledge you’ve learnt here today and the revision that you’ll be doing from now until the exam, you’ll be able to decrease the number of issues you run into and push through any roadblocks you do encounter!
