This is the question that keeps retake students awake, so here is the answer without hedging. The overwhelming majority of UK universities accept A level retakes and make offers on the improved grades exactly as they would on first attempt grades. A small number of courses, concentrated in Medicine, Dentistry and Veterinary Medicine, apply extra conditions or occasionally do not consider resitting applicants at all. Those courses state their position publicly, and you can check every one of them before you commit to a year.
Why the fear is bigger than the fact
The worry is inherited from an older admissions culture, and it persists because it is rarely contradicted directly. In practice, admissions tutors are making a prediction about whether you will cope with the course. A student who came back, worked for a year and turned a C into an A has produced fairly direct evidence about how they respond to difficulty. That is not a mark against you.
The numbers bear it out. In 2026, 94% of our A level retake students were placed at Russell Group universities. Those are not students who were quietly forgiven for retaking. They applied with retake grades and were made offers on them.
The exceptions, stated plainly
The genuine restrictions cluster in a few places.
Medicine, Dentistry and Veterinary Medicine. Some schools do not consider applicants who are resitting. Others do, but require higher grades from resitting candidates than from first time applicants, or require that the resit was caused by documented extenuating circumstances such as illness or bereavement. Policies differ from one medical school to the next and they change between admissions cycles, so a list here would be out of date within a year. Read the current entry requirements page for each specific school.
A small number of highly competitive courses elsewhere. Occasionally a course will say it prefers first attempt grades. This is uncommon outside the health professions, and where it appears it is usually a preference expressed in a contextual statement rather than a hard bar.
Course specific subject rules. These are not really about retaking at all. A course that requires Chemistry at grade A requires it whenever you sat it.
That is the whole list. Everything else in the sector, including every Russell Group university for the large majority of its courses, treats a retake grade as a grade.
How to check a course properly
Do this before you choose your subjects for the year, not in the spring.
- Find the course page on the university’s own website, not on an aggregator. Aggregators summarise and summaries lose exactly the detail you need.
- Read the entry requirements section in full, including any separate page for the department’s admissions policy.
- Search that page for “resit”, “resitting” and “second attempt”. If nothing appears, the course has no separate policy, which means the standard offer applies to you.
- If anything is ambiguous, email the admissions office and ask directly. Put your actual situation in the email: which subjects you are retaking, why, and what grades you already hold. Admissions offices answer this question constantly and they answer it honestly.
Keep the replies. If a course confirms in writing that it will consider you, that is worth having in August.
What you should declare
Declare everything. Your UCAS application lists all qualifications and all attempts, including the grades you are not proud of. Universities receive your full results record anyway, so there is nothing to be gained by omission and a withdrawn offer to be lost by it.
The place to deal with the story is not the qualifications section but the personal statement and the reference. One clear sentence about what happened and what you did about it is far stronger than silence. Admissions tutors read thousands of statements; the ones that explain a dip and then move on to the subject are consistently better received than the ones that pretend the dip did not happen.
The version of this that actually matters
The real question is not whether universities accept retakes. It is whether your retake year will produce grades that make the question academic.
That comes down to how the year is taught. A year spent sitting at the back of a class of twenty five, listening to content you have already heard once, will not move a C to an A. A year built around one to one teaching, a diagnosis of what went wrong the first time, and weekly individual mentoring generally will. Our students improve by 1.5 grades on average.
If you want to know what that would look like for your subjects, our guide to retaking A levels covers the mechanics, and you can talk to the college directly.
