The TMUA is run by UAT-UK, the joint organisation set up by Imperial College London and the University of Cambridge, and sat at Pearson VUE test centres.
Scoring
Results come back as a single score from 1.0 to 9.0. There is no negative marking, so every question should be answered, including the ones a student never got to read properly. That sounds obvious and is routinely forgotten at minute 74.
Who uses it
Seven universities use the TMUA for 2027 entry: Cambridge, Oxford, Imperial, LSE, Warwick, Durham and UCL. Oxford retired the MAT in January 2026, so Maths and Computer Science applicants there now sit this test as well. UCL requires it for Economics (L100 and L101). Warwick makes it compulsory for Computer Science and Mathematics but recommended for Economics and MORSE. Durham uses a 5.0 or above to cut the grade offer. Sheffield, Lancaster and Bath do not use it, whatever older guides say.
Required, recommended and merely accepted are three different things, and the lists move between cycles. Check the university's own course page for your year of entry rather than trusting any tutoring website, including this one.
Timing
The test is normally sat in October of Year 13, alongside the UCAS application. Cambridge applicants must take the October sitting. Registration closes well before the test date and schools sometimes miss it, so confirm the deadline with the exams officer early.
