How TMUA scoring actually works
Each TMUA paper has 20 multiple-choice questions and there is no negative marking: one mark for a correct answer, zero for a wrong or blank one. So you should always attempt every question. Your raw marks across the two papers are then converted to a single overall score on the 1.0 to 9.0 scale, reported to one decimal place. For the full mechanics, see our TMUA scoring guide.
Why this is only an estimate
UAT-UK, which runs the test, does not release a public raw-to-scaled conversion table, and the boundaries are re-set for every sitting based on how hard that paper turned out to be. This calculator therefore anchors to the facts that are public: the national average is around 5.4, roughly 14 to 15 correct per paper tends to land near a 6.0 to 7.0 band, and about 17 or more per paper is near 7.5 and up. It is a sensible ballpark, not an official prediction. For what counts as a competitive score, see what is a good TMUA score.
How to push your band up
The fastest gains come from Paper 2 reasoning (logic, proof and counterexamples), which most applicants underprepare, and from speed under the no-calculator, four-minutes-a-question pressure. The single best way to improve is volume on real, well-explained questions. Our preparation plan turns that into a week-by-week schedule.
