How to prepare for the ESAT
ESAT revision works best when it is narrow. You only sit the modules your course asks for, and each one is short and fast, so once you know exactly what you face you can put all your time where it counts.
If you are starting from scratch
With no preparation yet, work in this order:
- Confirm which three modules your course requires.
- Read the official subject guide for each of your modules.
- Close content gaps one topic at a time.
- Practise questions by topic within each module.
- Move to full timed modules, starting with the official specimen tests.
- Add the retired NSAA and ENGAA papers for extra timed practice.
- Analyse every mistake, then repeat under exam conditions.
The sections below expand each step.
Confirm your ESAT modules first
Before anything else, find out which three modules you need. Mathematics 1 is compulsory, and the other two are fixed by your course. A Cambridge Engineering applicant sits Mathematics 1, Mathematics 2 and Physics; a Natural Sciences applicant may choose two sciences. Check your combination on our university requirements pages or in which ESAT modules you need. There is no sense revising Biology for a course that never tests it.
Use the official ESAT specifications
Each module has its own subject guide setting out what you are expected to know. Read the official ESAT preparation materials for your modules and treat each one as a checklist. Our topic-by-topic textbook then covers those topics so you can rebuild any weak area before you move on to timed papers.
Practise under ESAT timing
The ESAT is deliberately tight, and this is where a lot of marks are won or lost. Twenty-seven questions in 40 minutes is about 89 seconds each, and the test is tight enough that answering every question is not the expectation.
That changes how you should play it. Suppose you hit a hard question early and dig in for four minutes. You might get it, but those four minutes were nearly three easier questions you never reached, each worth the same single mark. So the winning approach is to take the marks you can bank quickly, flag the rest, and only return to the hard ones with the time left over. Our article on running out of time in the ESAT sets out a simple system for doing this under pressure.
Two rules make the rest easier. Because nothing is deducted for a wrong answer, answer every question even when you are guessing. Because no calculator is allowed, keep all your working by hand from day one, so mental arithmetic stays quick.
An ESAT revision plan
A sensible shape for a two-month run, stretched or compressed to fit your time:
| Weeks | Focus |
|---|---|
| 1 to 2 | Confirm your modules, work through each specification, close content gaps with the textbook |
| 3 to 5 | Topic practice per module, then start timed sets within a single module |
| 6 to 7 | Full timed modules, official specimen tests, then retired NSAA and ENGAA papers |
| 8 | Final timed modules under exam conditions, review-led, focused on repeat mistakes |
Start with the official specimen tests, which run in the same on-screen player as the real exam, so the interface holds no surprises on the day. You can drill timed papers and target weak topics with our past papers and adaptive practice.
Key dates
For 2027 entry the ESAT is sat at Pearson VUE centres from 12 to 16 October 2026, with booking closing on 28 September 2026. A January 2027 window exists for applicants to some universities, but Cambridge and Oxford applicants must sit in October. The fee is 78 pounds for candidates in the UK and Republic of Ireland, and bursaries are available for eligible UK candidates if you apply before you book. Confirm every date on the UAT-UK deadlines page.
Official ESAT resources
The ESAT is set and run by UAT-UK, a partnership between Imperial College London and the University of Cambridge, and these are the authoritative sources. Read them first. Everything on esat.fyi is supplementary practice built around them, including the topic-by-topic textbook, the question bank and timed practice.

Frequently asked questions
How long do I have per ESAT question?
Each module gives you 40 minutes for 27 questions, roughly 89 seconds each. The test is tight by design, and finishing every question is not the expectation, so how you spend that time matters as much as what you know.
Which past papers should I use for the ESAT?
Start with the official ESAT specimen material, then practise with the retired NSAA and ENGAA papers, which share the ESAT's question style. Always work under timed conditions and review your mistakes.
Can I choose which ESAT modules to sit?
Mathematics 1 is compulsory for everyone. The other modules are set by the course you apply to, so confirm them against your university's requirements before you start revising.
Is a calculator allowed in the ESAT?
No. No calculator is permitted, so practise all arithmetic and algebra by hand throughout your preparation.
How long should I spend preparing for the ESAT?
For many students, around two to three months of regular, timed practice is a workable amount. Frequent short sessions work better than occasional long ones, because the test rewards fast, confident recall.
