What to do in the exam hall

The exam hall is a strange environment. You will have spent weeks preparing for it, and yet relatively little attention is paid to what happens once the paper is in front of you, from the moment you open it to the moment you hand it in.

The claim here is that sitting an exam well is itself a skill, and like any other skill it can be practised and improved. The instincts that feel most natural under exam pressure are often not the instincts that produce the best results. Understanding why they go wrong, and having a plan for overriding them, is the most useful preparation you can undertake in the period immediately before an exam.

The hours immediately before an exam are not a good time for intensive revision. You will not consolidate new knowledge effectively at this stage, and attempting to is likely to increase anxiety without improving performance. Spend the final hour in ways that calm rather than agitate: a short walk, a light meal if the timing permits, a review of plans and structures you have already prepared rather than new material.

Attend to logistics in advance. Prepare your equipment the night before, know where the hall is, and allow more than enough time to arrive. The stress of a late or uncertain arrival is entirely avoidable and entirely counterproductive.

Do not engage in anxious conversation with other candidates beforehand. Comparing levels of preparation, or speculating about likely questions, rarely helps and often unsettles. Most people, in the minutes before an exam, are not accurate reporters of what they know.

When the paper is placed in front of you, resist the impulse to begin writing. The instinct to start is natural: time feels precious, and writing feels like progress. But beginning before you have read the whole paper is one of the most common and most costly mistakes candidates make.

Read the entire paper before committing to any question. Note your initial response to each, but do not act on it. A question that looks straightforward at first glance may on reflection be more constrained than it appears; one that initially seems difficult may turn out to be well suited to what you know. First impressions under pressure are unreliable, and the few minutes spent reading the whole paper are rarely wasted.

Pay attention to the instructions. Confirm how many questions you are required to answer, whether there are compulsory sections, and what the rubric specifies. Misreading them is less common than sometimes suggested, but it does happen, and the consequences are severe.

The single most consequential decision you will make in an exam is how to divide your time. Work it out before you begin writing, not during. Three questions in three hours is sixty minutes each. Be precise: note your intended start time for each question, and commit to moving on when that time has elapsed.

The psychology is worth understanding. Candidates who overrun on questions they feel confident about usually do so because they believe the additional time is producing proportionally more marks. It is not. The relationship between time and marks is not linear: a question given forty minutes rather than sixty will, in most cases, score far closer to the sixty-minute mark than the reduction in time suggests. A question given ten minutes rather than sixty can produce a mark low enough to undo everything achieved elsewhere on the paper.

The implication is clear. The safest strategy, at every level, is to give equal time to each question, and to adhere to your timings even when doing so feels uncomfortable.

Daniel Kahneman, in his work on cognition, identifies two modes of thought: System 1, which is fast, instinctive and associative, and System 2, which is slower, deliberative and analytical. Both have their place in an exam, but they are suited to different tasks.

When you first look at a question, System 1 activates immediately. Relevant knowledge comes to mind, initial ideas form, and the rough shape of a response begins to suggest itself. This is useful and should not be suppressed. But System 1 is poorly suited to constructing an argument, weighing competing interpretations, or organising evidence coherently. Those require System 2, and System 2 takes time and deliberate effort to engage.

A practical method for managing the transition: when you first meet a question, spend a minute or two writing down everything that comes to mind, unfiltered and unorganised. That gives System 1 something to do and captures what it produces. Then set it aside and think carefully about the question itself. What is it actually asking? Can its terms be read in more than one way? What would a strong argument look like, and what evidence would it need? This second phase is where planning proper begins.

Only once you have a clear sense of your argument should you begin to write. An answer produced after genuine planning, even if only five to ten minutes are given to it, will almost always be more coherent and more persuasive than one written straight through, however fluent that unplanned writing appears.

In a timed examination, clarity is more valuable than elaboration. A well-constructed, direct argument that addresses the question precisely will, in almost all marking contexts, outperform a longer response that wanders or repeats itself. This is not an invitation to brevity for its own sake, but a reminder that the instinct to keep adding material is not always productive.

If you find yourself stuck on a section, move on and return to it at the end if time permits. A response with an underdeveloped section is far preferable to one that never reaches its conclusion.

In the final minutes, resist the temptation to submit early. If you have finished with time remaining, use it to review what you have written: check for logical gaps, incomplete sentences, and arguments that have not been brought to a conclusion. Small improvements made here can, at the margin, be significant.

Avoid the detailed post-mortems candidates often conduct immediately after an exam. They rarely produce accurate assessments of how anyone has done, and they frequently generate unnecessary anxiety about answers that have already been submitted.

If you have another examination, rest first. The inclination to begin revising immediately after sitting a paper is understandable, but the evidence on cognitive fatigue suggests it is rarely the most productive use of that time.

Reading the full paper before committing, planning every answer before writing, allocating time precisely and sticking to it, and managing the transition from fast to slow thinking apply to examinations at every level and in every subject. They are also, to a significant degree, counter-intuitive: they require you to resist impulses that feel natural under pressure. That is precisely why practising them in advance, in mock conditions where possible, is so valuable. By the time you sit the exam itself, they should be established well enough that they no longer require conscious effort.
