Cambridge Assessment Admissions Testing is working with the University of Oxford to assist in the administration of its Mathematics Admissions Test (MAT).
The MAT is a paper-based test. It is a 2-hour 30-minute, subject-specific admissions test for applicants to the University of Oxford’s undergraduate degree courses in Mathematics, Computer Science and their joint degrees.
