Some stress before an exam is useful — it sharpens attention and it is what gets people to revise at all. The problem is not the presence of stress, it is when it tips into the range where recall gets worse rather than better.
General information, not medical advice. If anxiety is persistently affecting your daily life, a doctor or your university’s support service is the right place to take it.
What actually helps
Doing past papers under real conditions
The single most effective anxiety reducer available, because most exam anxiety is uncertainty about the situation rather than the content. Having already sat through the format, the time pressure and the feeling of not knowing question three removes the novelty.
Timed, closed-book, no stopping. The discomfort is the point — you are rehearsing the conditions, not just the material.
Sleep, boringly
Sleep deprivation and anxiety amplify each other in both directions. Protecting sleep in the final week does more for performance than the extra hours would have, for reasons covered in our piece on sleep as a study technique.
Slow breathing, specifically longer out than in
Four seconds in, six or seven out, for two minutes. This is not a relaxation cliché — extending the exhale engages the physiological system that slows heart rate, and it works in the exam hall without anyone noticing.
Movement
A twenty-minute walk reliably reduces acute anxiety. It is also the easiest thing to cut during exam season, which is precisely when it is most useful.
Writing the worry down
Ten minutes of writing about what you are anxious about, before an exam, has been found in several studies to improve performance — particularly for people who are usually anxious. The plausible mechanism is that it offloads the rehearsal that would otherwise occupy working memory during the exam.
What feels like helping and is not
Reassurance-seeking. Asking friends repeatedly whether the exam will be alright relieves anxiety for about ninety seconds and strengthens the pattern. It also tends to make everyone involved more anxious.
Comparing revision with classmates. Almost always ends with you feeling behind, and the information is unreliable — people misreport in both directions.
More caffeine. The physical symptoms of high caffeine intake and the physical symptoms of anxiety are close to identical. Past a moderate amount you are manufacturing the feeling you are trying to escape.
Cramming to feel prepared. Past a point, additional hours are being spent to reduce guilt rather than to learn, and they cost the sleep that would have helped more.
Post-mortems with friends after the exam. The answers you got wrong cannot be changed, and you have another exam on Thursday. Leave, walk, and do not compare answers.
The night before
- Stop revising at a time you decide in advance. A fixed stop is more valuable than the extra hour.
- Pack everything — documents, pens, water, calculator — so nothing is a decision in the morning.
- Check the time and place. Twice. Do not rely on memory for this.
- Do something absorbing and unrelated for an hour.
- Normal bedtime. Lying awake for a while is fine and much better than staying up.
In the hall
If your mind goes blank, it is almost always a temporary physiological response rather than lost knowledge. Put the pen down, breathe out slowly for thirty seconds, then start writing anything at all on the easiest question. Recall typically returns once you are producing rather than searching.
Afterwards
When results arrive, work out where you actually stand with the SGPA calculator rather than sitting with a vague sense of how it went. A number, even a disappointing one, is easier to act on than an impression — and it is usually less bad than the impression.
