Summary

The Engineering and Science Admissions Test (ESAT) is a subject-specific, computer-based exam required for undergraduate applicants to Cambridge and Imperial College London for courses like Engineering, Natural Sciences, Veterinary Medicine, and Chemical Engineering & Biotechnology. The test consists of 40-minute multiple-choice modules, with Mathematics 1 being compulsory for all. Students choose additional modules based on their course. There’s no pass or fail; only your correct answers are scored. Preparation involves revising subject fundamentals, practicing timed questions, and using official resources. Early registration and applying for access arrangements or bursaries (if applicable) are essential. A strong ESAT score can significantly boost your admission chances—making dedicated preparation a must.

Introduction

Are you applying to Engineering, Natural Sciences, Chemical Engineering, or Veterinary Medicine at the University of Cambridge or Imperial College London?

Then get ready to take the Engineering and Science Admissions Test (ESAT) which is a newly introduced admissions assessment designed to evaluate core scientific and mathematical skills required for some of the most competitive STEM programs in the UK.

In this comprehensive guide, we’ll walk you through everything you need to know about the ESAT 2025, including the format, modules, preparation strategies, deadlines, and how it fits into your university application.

What is the ESAT?

The Engineering and Science Admissions Test (ESAT) is a computer-based admissions assessment introduced by Cambridge and adopted by Imperial College London for specific STEM courses.

It’s designed to evaluate your understanding of core scientific principles and problem-solving skills in subjects like Maths, Physics, Chemistry, and Biology. There’s no pass or fail, but the scores play a critical role in the shortlisting process for interviews and final admission decisions.

Who Needs to Take the ESAT?

You must take the ESAT if you are applying to Cambridge for any of the following undergraduate courses:

  • Engineering
  • Natural Sciences
  • Veterinary Medicine
  • Chemical Engineering and Biotechnology

You also need to take the ESAT if you’re applying to Imperial College London for STEM-based programs like Engineering, Physics, or Natural Sciences.

Important Note: If you’re applying to both Cambridge and Imperial, you only need to take the ESAT once, but it must be in the October sitting.

ESAT Test Format

The ESAT is made up of multiple-choice modules, each lasting 40 minutes. You will take them back-to-back on the same day.

How is the ESAT Scored?

  • Your final score is based on the number of correct answers.
  • There are no penalties for incorrect answers, so it’s worth attempting every question.
  • Cambridge and Imperial will interpret your scores in the context of the rest of your application—such as predicted grades, personal statement, and interview performance.

ESAT Fees and Bursaries

  • There is an entry fee to take the ESAT.
  • If you’re a UK candidate facing financial hardship, you can apply for a bursary voucher to take the test free of cost.
  • Applications for bursary vouchers open on 24 June 2025 on the official ESAT website.

Access Arrangements

If you usually receive special accommodations for school exams (like extra time or use of a reader), you can apply for similar access arrangements for the ESAT.

  • Apply starting 24 June 2025
  • Deadline: 8 September 2025
  • You may be required to submit supporting documentation

How to Prepare for the ESAT

The ESAT isn’t a test of how much you’ve memorized, but how well you apply concepts under time pressure. The modules are grounded in A-level and IB-level content, so your school curriculum does help, but targeted preparation is essential.

  • Review your core concepts in maths and sciences based on your chosen modules.
  • Use official ESAT practice materials available on the ESAT website.
  • Solve previous year papers of similar tests (like the old NSAA or ENGAA, if available).
  • Time yourself strictly—you get just 40 minutes per module.
  • Focus on accuracy + speed, as there’s no negative marking.

Conclusion

The Engineering and Science Admissions Test (ESAT) is now a crucial gateway for top STEM programs at Cambridge and Imperial. It challenges students on their logical application of core science and maths principles, and it’s your chance to stand out beyond grades and statements.

Don’t wait until the last moment. Smart, early preparation with real-time practice and the right support can make all the difference.

Frequently Asked Questions(FAQs)

1. Is the ESAT compulsory for all Cambridge applicants?
Ans: No, the ESAT is only required for those applying to specific STEM courses like Engineering, Natural Sciences, Veterinary Medicine, and Chemical Engineering & Biotechnology.

2. What level of difficulty is the ESAT?
Ans: The ESAT assesses A-Level or IB-level understanding in Maths and Science. While it's rigorous, consistent practice and a good grasp of concepts can help students perform well.

3. Do I need to attempt all questions in each module?
Ans: Yes, you should. There’s no negative marking, so even educated guesses can work in your favor.

4. How many modules do I take in the ESAT?
Ans: All students must take Mathematics 1. Depending on your course, you take two additional modules (totaling 3 modules or 120 minutes).

5. Will the same ESAT score be used for both Cambridge and Imperial?
Ans: Yes. If you’re applying to both universities, you only take the test once in October, and both institutions will access the same score.
