By Cyril KimbiExam anxiety is not the same as being unprepared, and treating it as though it were is what makes it worse. Candidates who know the material can still lose marks to a physiological response that has nothing to do with what they know — and that response is trainable.
Why it costs you marks
Anxiety does not simply feel unpleasant. It occupies working memory — the small mental workspace where you hold a question while manipulating it.
When part of that workspace is taken up by monitoring your own panic, less remains for the multi-step calculation in front of you. This is why the experience is so specific: you go blank on something you demonstrably know, and it returns the moment you leave the hall. Nothing was forgotten. The workspace was simply full.
Understanding this changes the goal. You are not trying to feel calm. You are trying to free up capacity.
The one intervention that does most of the work
Practise under real exam conditions, repeatedly. Not reading notes, not doing questions with the book open — a full paper, timed, no interruptions, no notes.
Anxiety is largely a response to unfamiliarity. The first time you experience the specific pressure of a clock and a sealed paper should not be in the examination hall. Ten timed past papers under conditions does more for exam anxiety than any relaxation technique, because it converts an unknown situation into a familiar one.
It also gives you evidence. “I panicked in the mock and still finished” is a fact you can recall in the hall, and facts are more useful than reassurance.
Breathing, done properly
“Take deep breaths” is close to useless as advice, because most people do it wrong and conclude it does not work. The mechanism is the length of the out-breath, not the depth of the in-breath.
- Breathe in through the nose for a count of four.
- Breathe out through the mouth for a count of six to eight.
- Repeat for about two minutes.
A longer exhale than inhale is what shifts the nervous system out of its alert state. It takes roughly ninety seconds to take effect, which means it must be started before you need it — in the queue, not halfway through question three.
Practise it during timed papers so it becomes automatic. A technique first attempted under real pressure usually fails.
Reframing instead of suppressing
Telling yourself to calm down rarely works, because you are asking your body to do something it has already decided against. The better-supported approach is reappraisal: interpreting the same sensations differently.
A racing heart, quick breathing and heightened alertness are the body preparing for effort. That is the same response an athlete has at the start line. The sensations of anxiety and of readiness are close to identical; what differs is the label.
Saying “I am ready, my body is switched on” is not positive thinking. It is a more accurate description of what is happening than “something is wrong with me”, and it is measurably more useful.
Write the worry down
Ten minutes of writing about your exam worries, shortly before the exam, has been shown to improve performance — particularly for the most anxious students.
The mechanism follows from the working-memory explanation: getting the worry onto paper stops it circulating in the space you need. Write freely, unedited, and do not attempt to solve anything. Then put it away.
The night before, and the morning
- Stop revising early. Cramming the night before adds little and costs sleep, which is where memory consolidates.
- Pack everything the night before. Every item found in the morning is a small shot of adrenaline you cannot afford.
- Eat. Sitting a three-hour paper on an empty stomach is a self-inflicted handicap.
- Arrive early, but not too early. Thirty minutes standing among panicking classmates is contagious. Arrive, stay slightly apart, breathe.
- Do not compare revision. The conversation in the corridor about what everyone else covered has never once helped anyone.
In the hall, when it happens
If the blank arrives mid-paper, the sequence that works is mechanical rather than emotional:
- Put the pen down for twenty seconds. Counterintuitive and effective.
- Breathe out long, three times.
- Move to a question you can definitely do. Marks are marks in any order, and success restores capacity.
- Return to the stuck question and write anything relevant — a definition, a diagram, a formula. Starting to write frequently unlocks the rest, and partial credit is real.
The temptation is to stare harder at the difficult question. That is the one response that reliably makes it worse.
When it is more than exam nerves
There is a line worth naming. If anxiety is present most days rather than around exams, if it produces panic attacks, if it stops you attending, or if it comes with persistent low mood or thoughts of harming yourself, that is not exam technique — that is health, and it deserves a doctor or a counsellor rather than a study guide. Seeking help early is not an admission of weakness; it is the same logic as treating an injury before an examination rather than after it.
Frequently asked questions
Is some anxiety useful?
Yes. Moderate arousal sharpens attention. The problem is the level past which it starts consuming working memory.
Why do I go blank when I knew it the day before?
Because retrieval competes for the same limited workspace the anxiety is occupying. The knowledge is intact; the access is blocked.
Do breathing exercises really work?
Yes, when the out-breath is longer than the in-breath and you start before the peak. They take about ninety seconds to act.
Should I take something to calm down?
Not without medical advice. Sedatives impair recall and reaction time, which costs more than the anxiety does.
What helps most overall?
Repeated timed practice under real conditions. It is preparation and anxiety treatment at the same time.
