ESAT Paper 4 Worked Solutions
Access high-quality worked solutions, concept breakdowns, and timing strategies for the ESAT Paper 4 modules. Redesigned to help Oxford and Cambridge applicants maximize test-day speed.
Available Subject Modules
Select a module below to view step-by-step worked solutions and timing benchmarks:
Mathematics
Geometry, circles and triangles, algebra, area, and probability including conditional probability. 27 worked solutions.
Advanced Mathematics
Sequences and series, binomial expansion, logarithms, functions and transformations, and combinatorics. 27 worked solutions.
Physics
Momentum and collisions, moments and equilibrium, circuits and power, waves, thermal radiation, and nuclear decay. 27 worked solutions.
Chemistry
Moles and quantitative chemistry, atomic structure and isotopes, redox, electrolysis, and equilibria. 26 of 27 worked solutions; the other 1 are marked as missing from our source scan.
Biology
Cell biology, enzymes, genetics, human physiology and hormones, and ecology. 27 worked solutions.
What is in Paper 4
This paper carries 134 of its 135 questions with a full worked solution. Four modules are complete; one Chemistry question is missing, because our archive copy of the source paper does not reproduce it. It is marked as missing on the page rather than filled in with a plausible-sounding guess.
- Chemistry: 26 of 27 worked, 1 marked as missing from the source scan.
If you want practice with no gaps in it at all, the 19 mock modules are complete throughout. Why we publish the gap rather than quietly close it is explained in our Quality Assurance standards.
Where to go next
- Sit a module against the clock: the 19 mock modules are 27 questions each, the same shape as one sitting of the real test.
- Recognise the method before you calculate: the ESAT Shortcut Library holds 105 methods, each linked to every question that drills it.
- Check what is actually examinable: the specification tables count every assessable sub-topic from the official document.
- Revise formulas and exam tactics: the ESAT Essentials guide.
