And Leeds I think does not require the UKCAT University of Leeds A100 : This is the only course in University of Leeds that requires the UKCAT according to its website. A 100 is in fact Medicine course So add it to the list of unis that you could apply to without sitting the test
www.ukcat.ac.uk lists all unis that do want ukcat tests for medecine or dentistry - so if its not listed its not required but check uni admissions details to be 100% sure.
