UK open-book exams are marked to a higher standard than closed-book ones, because examiners assume access to sources and therefore reward application and judgement rather than recall. Students who prepare by gathering more notes usually perform worse than those who prepare by practising the analysis.
What Changes When the Book Is Open
In a closed-book exam, reproducing a framework accurately earns marks. In an open-book exam it earns almost none, because anyone can copy it out. The marks move to what you do with it: selecting the right framework, applying it to unfamiliar material, and defending the conclusion.
UK examiners commonly report that open-book averages are lower than closed-book averages for the same module. Students expect an easier paper and prepare accordingly.
The trap: time spent searching notes during the exam is time not spent writing. Students with 200 pages of material typically score below those with a two-page decision sheet, because the second group is answering while the first is still looking.
Prepare a Decision Sheet, Not a Library
One or two pages containing:
- A framework selector. "Question about industry attractiveness → Five Forces. About internal advantage → VRIO. About macro change → PESTLE."
- The key formula or step sequence for anything calculated.
- Three or four go-to sources with author, year and the one claim each supports.
- A paragraph template for the analytical move: claim, evidence, implication, limitation.
Everything else stays available but unindexed. You are building an index, not a repository.
Time Allocation
For a three-hour open-book paper with three equal questions:
- 10 minutes reading and choosing questions
- 5 minutes planning each answer before writing it
- 45 minutes writing each
- 10 minutes checking
Answering two questions superbly and one poorly scores worse than three good answers, because marks are capped per question. Always start the final question.
Take-Home Papers
A 24-hour or 48-hour take-home is a different animal again. Expectations rise further: proper referencing, coherent structure, no typographical errors. Treat it as a short essay under time pressure, not a long exam.
Two cautions. First, collusion rules still apply — discussing the paper with classmates is misconduct at most UK institutions even though you are at home. Second, the same academic integrity rules on AI apply, and take-home papers are routinely run through similarity and AI detection.
What Markers Reward
- Choosing the appropriate framework and saying why the alternatives fit less well
- Applying it to the specific material in the question rather than in general
- Acknowledging what the framework cannot show
- Reaching a defended conclusion instead of listing considerations
Copying a definition from your notes earns nothing. Using it to reach a judgement earns everything.
Frequently asked questions
Are open-book exams easier?
No. UK examiners mark them to a higher standard because access to sources is assumed, so recall earns almost nothing and the marks move to application and judgement. Averages for open-book papers are frequently lower than for closed-book versions of the same module.
What should I prepare for an open-book exam?
A one or two page decision sheet rather than a large set of notes: a framework selector, key formulas or step sequences, three or four go-to sources with the claim each supports, and a paragraph template for the analytical move. Searching during the exam costs more than it returns.
Can I discuss a take-home exam with classmates?
Usually not. Collusion rules continue to apply during take-home assessments at most UK institutions, and discussing the paper is treated as academic misconduct even though you are working at home. Check the instructions, which normally state this explicitly.
Do take-home exams get checked for plagiarism?
Yes. Take-home and open-book submissions are routinely run through Turnitin similarity checking and AI writing detection, in the same way coursework is. Referencing conventions also still apply.
