The short answer
UAT-UK does not publish an official hardest-paper ranking. We recommend saving 2022 and 2023 for late-stage full-paper rehearsals because they are the most recent released papers, not because UAT-UK has rated them as objectively harder. A student who is weaker at logic may experience a different order from one who loses time on algebraic manipulation.
What “hard” should mean
A useful comparison looks beyond the number of advanced-looking questions. We use five dimensions because a paper can be conceptually modest and still be severe under the clock.
A useful way to group the released papers
This grouping is intentionally broader than a league table. The difference between adjacent years is less important than the difference between sitting a paper unseen and sitting it after seeing its questions discussed online.
Specimen and 2016–2019
These papers are valuable for building a stable reference. They reveal the language, breadth and multiple-choice structure without needing to serve as your final prediction of test-day performance. Do not mistake “earlier” for “easy”; individual questions can still be excellent high-level practice.
2020–2021
Use these once the format is familiar. They are a useful bridge between early archive work and the strongest late-stage checks, particularly when reviewed for decision-making rather than only topic labels.
2022–2023
Keep at least one of these untouched until your preparation is mature. Their value is greatest as a complete timed experience. If you split every question into topic drills first, you lose the chance to measure recognition and pacing across a whole paper.
Build your own evidence-based ranking
Sit papers in full conditions and record more than the raw mark. A fair personal comparison uses the same environment, the same timing and no previous exposure.
Paper 1 and Paper 2 separately.
Questions not reached or abandoned.
Marks that cost more time than they should.
Knowledge, recognition, method, execution or decision.
Why score conversions complicate comparisons
The TMUA scale is designed so that performance can be interpreted across different forms of the test. That means the same raw mark need not represent the same scaled score every year. Use published historical conversion tables where available, and label any conversion for a new mock as an estimate.
A paper that gives you a lower raw mark is not automatically “harder” in an admissions sense. It may be harder for your profile, or it may be a form where the conversion compensates for overall difficulty.

{{ boundarySummary }} A lower threshold means that year's table awarded the selected historical score at a lower raw mark. It suggests a more generous conversion in that score region; it does not prove that every question, paper or candidate experience was harder. 2016 is an official pre-launch practice-paper table. The 2023 line is dashed because the original provider download is unavailable and the values come from a preserved transcription.
A sensible order for practice
- Use the specimen to learn the format.
- Choose an early paper for diagnosis.
- Use the middle archive for targeted and mixed work.
- Protect one 2022 or 2023 pair for a late, full-condition rehearsal.
- Use original mock papers when the official archive is no longer unseen.
Difficulty only helps when it is credible.
Use original papers built around the official specification and the demands visible in released material.
