Test structure & modules

The ESAT has five modules. Mathematics 1 is compulsory for all candidates: everyone sits it. You then sit the additional modules required by your specific course, typically two more, for a total of three modules:

• Mathematics 1 (compulsory): number, algebra, sequences, geometry, trigonometry, functions, calculus, statistics and probability.
• Mathematics 2: extends Maths 1 into further calculus, differential equations, complex numbers, matrices, and proof. Required for most engineering-track courses.
• Physics: mechanics, waves, electricity, magnetism, thermal physics, quantum and nuclear physics. Assumes Maths 1 throughout.
• Chemistry: atomic structure, bonding, energetics, kinetics, equilibria, organic chemistry, spectroscopy. Assumes Maths 1 throughout.
• Biology: cells, genetics, biochemistry, physiology, ecology and evolution. Assumes Maths 1 throughout.

All five modules assume the content of Mathematics 1. This applies to the science modules too; questions in Physics, Chemistry, and Biology draw heavily on algebraic manipulation, proportional reasoning, and quantitative methods from the Maths 1 specification.

Each module contains 27 multiple-choice questions with a time allowance of 40 minutes. Modules are separately timed: the clock resets between modules, and unused time from one module cannot carry over to the next.

For a typical candidate sitting three modules, total active test time is 120 minutes. Between modules there is a short timed break shown on screen; you can leave the room to use the toilet or have a drink of water, but the timer continues, so you must be back before it expires or you will lose time from the next module.

You are provided with a notebook and pen for rough working. You may not bring your own paper or notes, and calculators are strictly prohibited. Check your pen works before the test begins; ask for a replacement straight away if it does not.
