Within their main admissions policy (
here) Leeds say, "The eligibility of students who are undertaking a further attempt at an entry qualification is an academic decision taken by the relevant school. Applicants in this situation should check the relevant school admissions policy or admissions guidance." There doesn't appear to be an applicable school-level admissions policy. You could contact
[email protected] for further information, if you like.
Exeter's admissions policy (
here) says that, "We are generally happy to consider those who have or are re-taking part or all of a qualification, subject to any caps or numbers management relating to the volume of unconditional offers overall." That might suggest that if they have too many applicants for Diagnostic Radiography, those who have re-taken a year might be at the back of the queue with respect to an offer.
Cardiff's School of Healthcare Sciences School of Healthcare Sciences (
here) says, "Applicants who have failed to achieve A-level grades (or an equivalent qualification) at first attempt will not usually be considered for Child Nursing (B732) and Midwifery (B720) programmes." They make no such statement about Diagnostic Radiography (B823).
Despite the above not being all positive news, the fact that you have received two Us in you end-of-year 12 exams makes is difficult to imagine that you would get the predicted grades you need for Diagnostic Radiography at the above universities. Perhaps it's worth look at some Diagnostic Radiography course which include a Foundation Year, as they will have lower entry requirements? For example,
this one at Plymouth say they want 32 - 48 UCAS points and
this one from Derby wants CDD.
