Understand how your five UCAS choices are counted, where special restrictions apply, and what you give up when several choices are used in the same place or subject area.
UCAS gives you up to five undergraduate course choices in one application. Each course counts as one choice, even when two courses are at the same university. You do not rank the choices when you apply, and universities do not receive a preference order.
A shortlist of five universities is therefore only one possible use of the system. You could also apply to several courses at the same institution or mix different subjects, provided the special restrictions described below are respected.
Several courses at one university still use several choices
If you apply for History and Politics and for History at the same university, you have used two choices. Courses with different course codes, campuses, start dates or entry points also count separately.
UCAS allows you to concentrate several choices at one university, and that university can see the applications you make to its own courses. Using three of your five choices there leaves only two for other institutions.
That concentration is sensible only if each course is one you would genuinely consider taking. It also reduces your ability to spread applications across universities with different entry requirements, course structures or admissions approaches. The Course Choice hub covers choosing between courses, while the University Options hub covers comparing universities.
Different subjects can share the same application
UCAS does not require all five choices to have the same course title or belong to one subject area. A mixture of single-subject, joint and combined degrees is allowed.
The practical constraint is the shared Personal Statement. Every choice receives the same statement, so a combination that makes sense administratively can still be difficult to support academically. If the subjects diverge sharply, check whether the reasons and evidence in the statement remain credible for every course receiving it.
Medicine, dentistry and veterinary subjects use a four-choice limit
You can apply to a maximum of four courses in any one of medicine, dentistry, veterinary medicine or veterinary science. Four medicine choices, for example, use four of the five available slots; the fifth cannot be another medicine course.
UCAS does not prescribe what the remaining choice must be. If you use it, choose a course you would genuinely attend and remember that it receives the same Personal Statement as the four restricted-subject choices.
These subjects also tend to bring earlier deadlines and admissions tests into the decision. Most courses in medicine, dentistry and veterinary medicine or science use the October equal consideration deadline, and individual courses may require a separate test. University Admissions Tests: Which Tests You Need and When to Take Them covers those requirements.
Oxford and Cambridge cannot normally both appear among your choices
Outside UCAS's graduate-medicine exception, you can apply to one course at either Oxford or Cambridge in the same cycle, not one at each.
UCAS lists a specific graduate-medicine exception. An applicant who will be a graduate at the start of the course and applies for Graduate Medicine A101 at Cambridge can also apply for Medicine A100 at Cambridge and Graduate Medicine A101 at Oxford, subject to the universities' additional instructions.
Oxford also limits standard undergraduate applicants to one Oxford course. A college preference or open application sits inside that course application and does not use another UCAS choice.
What universities can see while decisions are being made
During the decision stage, a university does not see the choices you made at other providers. If you applied to more than one course at the same university, it can see those applications because they are its own.
After decisions have been received on all choices and you have replied to any offers, UCAS makes the other choice details visible to providers. Until then, the rest of your shortlist is not part of another university's offer decision.
You can leave a choice unused
UCAS sets a maximum of five choices; it does not require you to use all five when you first submit. Leaving one unused gives no admissions advantage, but it can preserve a slot while you decide on a later-deadline course.
This is particularly useful when an October-deadline application is ready but one January-deadline choice is not. UCAS allows you to submit the early choices and add the later one afterwards, provided you remain within five choices and meet the later course's own deadline. The UCAS Application Timeline and Key Deadlines sets out those dates.
Current UCAS change rules also allow unused choices to be added after submission before 30 June if you have not replied to any offers. The new course's deadline still applies. An unused slot does not reserve a place or extend equal consideration.
The same application supports every choice
Your qualifications, reference and Personal Statement are part of one UCAS application rather than separate applications for each university. Each provider assesses that shared material against the course you applied to there.
After submission, replacing a choice, withdrawing from a course or adding an unused choice is governed by the post-submission rules. How to Change Your UCAS Application After Submitting covers those mechanisms and deadlines.
