The Engineering and Science Admissions Test (ESAT) at the University of Cambridge is designed to assess candidates’ aptitude in key areas of mathematics and the sciences. The ESAT is structured into two major parts: Mathematics 1, which is compulsory for all candidates, and Part 2, which consists of two additional modules from Biology, Chemistry, Physics, and Mathematics 2. Each section is composed of multiple-choice questions that evaluate both theoretical understanding and practical problem-solving abilities. Below, I will provide a detailed breakdown of the topics covered in the Cambridge ESAT.
