Engineering and Science Admissions Test (ESAT)

The ESAT is a computer-based test, which is made up of a number of modules.

Each module lasts 40 minutes and has 27 multiple choice questions. You will sit the modules back-to-back on the day of the test.

ESAT modules

Imperial courses using the ESAT require all candidates to sit the following modules:

• Mathematics 1
• Mathematics 2

If you're only applying to Imperial's Dyson School of Design Engineering, these are the only two ESAT modules you need to sit.

If you're applying to another department, you will also need to sit a third ESAT module – either Chemistry or Physics.

Find out which modules are required for your department of interest in the table below. You will need this information when you book. You will not be able to change the modules you have registered for on the day of the test.

How the test is marked

Your final scores are based on the number of correct answers you give. There is no pass or fail so you should aim to do the best you can.

You do not lose marks for wrong answers, so it’s worth attempting all questions.   

There will be two test sittings for the ESAT for 2026 entry:  

• Thursday 9 and Friday 10 October 2025
• Tuesday 6 and Wednesday 7 January 2026 

Candidates can book a time slot on any of these test days though please note that tests in China will be available on only one day per test sitting. They will take place on the second day listed above for each test. For more details, please visit the UAT-UK website. 
 
You should take the test just once for courses starting in 2026 entry as only your first test score will be used by selectors. 

If you will be sitting the test for the first time this year then you will first need to create a UAT-UK account with Pearson VUE. 
 
You'll be able to do that using a link that will be available on this page within the UAT-UK website in June.
 
It is your responsibility to book and sit your test within the testing window.

Access arrangements, such as rest breaks or extra time, are available if you have:

• a learning difficulty
• a physical or mental disability
• a sensory impairment
• other medical condition that might impact your ability to sit your test

You should let UAT-UK about your requirements at least 10 working days before you intend to book your test.

You should wait for your access arrangements to be confirmed before booking the test in your chosen Pearson VUE test centre.

Find out more about applying for access arrangements.

ESAT is currently used by Imperial College London and the University of Cambridge for selection to courses in engineering and sciences. 

If you’re applying to both universities, you only need to take the ESAT once, but you must take the test in the October sitting.

There is an entry fee for the ESAT:

• £75 for candidates sitting the test in the UK and Republic of Ireland
• £130 for candidates sitting the test anywhere else in the world

Test fees are determined by the test centre location, not on your place of residence or nationality.

Bursary for UK candidates
