The fifth UCAS choice

The four-course rule, and where UCAS states it

A UCAS application carries up to five course choices. For medicine, dentistry and veterinary medicine there is a long-standing restriction on top of that: a student may apply to a maximum of four courses in any one of those subjects. UCAS's application page states that for these subjects you can only apply to a maximum of four courses in any one of medicine, dentistry, veterinary medicine or veterinary science. So the fifth choice cannot be a fifth course in the same subject.

Two details are easy to miss. The first is the phrase "any one of": the cap applies within each subject, not across them. A student can therefore apply to four medicine courses and one dentistry course, or split the five choices another way, as long as no single subject has more than four. The fifth choice can also be an unrelated course, or left blank. The second is that veterinary medicine and veterinary science are the same subject for this purpose. Course titles differ between universities, but a student cannot get round the cap by mixing the two.

UCAS can change the wording between cycles, so check the source before quoting any summary, this one included: UCAS page on filling in your application, last checked 7 October 2026.

How universities treat the fifth choice

First, the reassuring part. A university does not see where else a student has applied. UCAS states that an applicant's choices will not know where else they have applied, so the fifth choice university has no way of knowing that the other four were medicine, and cannot mark a student down for being a medicine applicant in disguise. Students often worry about this; they need not. Source: UCAS on what happens once it receives an application, last checked 7 October 2026.

Now the catch. One personal statement is shared across all five choices, so every university reads the same document. A statement built entirely around medicine arrives at the fifth choice university unchanged. That university cannot see the four, but it can see the statement is not about its course. UCAS acknowledges this for these applicants and advises contacting the universities concerned, since some are happy to be a fifth choice despite the statement.

So where the fifth is in a different subject and the statement cannot serve both, the fifth should go to a university that either does not use the personal statement to select for that course, or has said it does not mind one written around medicine. Do not assume either from the website. Have the student phone the admissions team, say they are applying for medicine, and ask whether the statement counts and whether they would still be considered. Few sixth formers think to do this, and it gets a straight answer. If the answer is no, that course is not a safe fifth. The UCAS guidance on writing a personal statement that works for multiple courses is a good page to share with the student (last checked 7 October 2026).

Watering down the statement is usually the wrong fix. The four choices are where the student's realistic offers are, and a statement hedged across two unrelated subjects is weaker for all five. Our guides to what a statement has to do are the medicine personal statement guide, the dentistry personal statement guide, and how medical schools use the personal statement. The change to the three question format is relevant too, because it changes how much room there is to cover two subjects at once.

When the fifth has to be decided

Medicine, dentistry and veterinary medicine share an early UCAS deadline in mid-October, months before the deadline for most other courses. That gives some useful, often missed, flexibility: UCAS states that choices with a different deadline can be added later, as long as the five choice total is not exceeded. So a student whose fifth is an ordinary degree with the standard deadline does not have to settle it in the same week as the four.

Some schools plan for this. The four go in on time, and November is spent researching the fifth: open days, course content, the job at the end, and a conversation about whether the student would take it. What you want to avoid is a student choosing in January with three rejections in hand. Put a date in the diary in November and treat it as a deadline.

Deadline dates and the rules around adding choices are set by UCAS and confirmed each cycle, so check the current position on the UCAS dates and deadlines page each year. On our side, the step by step UCAS guide for medicine walks the whole form, and the Year 13 checklist puts the fifth choice review in the right month alongside everything else the autumn contains. The Year 12 checklist is where the groundwork for a credible fifth starts, since relevant work experience cannot be arranged in October.

Dentistry and veterinary medicine work differently

In dentistry, the neighbouring professions are close neighbours. Dental hygiene and therapy is a clinical career with its own training and progression, and it makes a sensible fifth choice for a student whose evidence is dental. A dentistry applicant putting their fifth on medicine is a normal application, and so is the reverse. What goes less well is a medicine applicant who adds dentistry in the final week with no dental evidence in the statement; a dental school will struggle to believe it.

Veterinary medicine is the tightest of the three. There are far fewer UK vet schools than medical schools, the four course cap therefore covers a much larger share of the whole sector, and the evidence a vet school expects, particularly animal handling experience across different settings, does not transfer readily to a medical or dental application. A vet applicant's fifth usually goes to a related bioscience or animal science degree, not another clinical subject, and the shared statement is a tighter constraint than for medicine. Gateway and foundation routes exist here too, but they work differently from the medicine ones.
