UK Exam Formats Explained: Open-Book, Take-Home Papers and the Viva
How open-book exams, take-home papers and vivas actually work at UK universities, and how to prepare for each format differently from a traditional closed-book exam.
Since the pandemic, UK universities have kept far more assessment variety than before — many students now sit no traditional closed-book exam at all in a given year. Each format rewards different preparation, and treating them all the same way is the most common mistake I see.
Closed-book exams
The traditional format: no notes, no internet, fixed time in an exam hall. Still common for foundational modules in law, medicine, sciences and maths. Preparation should focus on active recall (practice answering past papers from memory) rather than re-reading notes, which feels productive but is a weak way to prepare for closed-book conditions.
Open-book exams
You can access set materials — sometimes just your own notes, sometimes any resource — during a timed exam, usually 2–3 hours.
Open-book exams are often harder to score well on than closed-book ones, because tutors assume you have the facts available and mark much more on analysis, application and argument quality. Students who spend exam time searching notes for facts they should already know consistently run out of time.
Prepare an indexed personal summary sheet in advance (even if not required) so you can find things fast rather than searching raw lecture notes live.
Take-home exams / papers
A set of questions released with a fixed window — commonly 24 or 48 hours — to complete and submit, treated with the same academic integrity rules as coursework (see our referencing and plagiarism guide).
- Read all questions first and plan your time budget across them before writing anything.
- Treat the writing itself like timed coursework — proper paragraphs, referenced evidence, a real conclusion — not exam-style bullet points.
- Submit well before the deadline; last-minute portal issues are not usually accepted as mitigating circumstances (see our guide on mitigating circumstances) if the window was generous.
The viva voce (oral exam)
A viva is a spoken examination, most commonly used for PhD defences but also appearing in some Master's dissertations, language degrees, and occasionally as a check on suspected misconduct. Two or more examiners ask you to explain, defend and expand on your written work.
Re-read your own submitted work as if you were a critical examiner, and prepare answers to the three questions you'd least like to be asked. Most vivas open with a broad, easy question ("talk me through your main argument") specifically to help you settle in — use it to establish confidence early.
What examiners are actually testing across formats
Regardless of format, UK exams consistently reward: a clear argument or answer stated early, evidence used to support rather than replace analysis, and explicit engagement with the specific question asked rather than a general essay on the topic. This lines up directly with the structural expectations in our essay and dissertation structure guide.
Accessibility and exam adjustments
If you have a disability, specific learning difference or health condition that affects exam performance, UK universities offer formal exam adjustments (extra time, rest breaks, separate rooms) through their disability service — see our guide on studying with a disability or dyslexia for how to apply, and gov.uk's guidance on disabled students for the wider funding picture.
Exam season logistics
Exam periods are stressful enough without also worrying about noisy accommodation or a difficult commute to campus. Arrive UK's accommodation service factors in exam-season considerations like quiet study space, and our pricing page details support packages that can be timed around your assessment calendar.
