A blackout in an exam means that knowledge you have learned suddenly seems out of reach. Many students experience this during written or oral exams. This guide explains what you can do in the moment and what helps before the exam.
Quick answer: A blackout is a short-term block. The psychosocial counselling service of the Studierendenwerk in Göttingen describes that the knowledge is usually not lost, only not retrievable at that moment. Short relaxation, a movement break and asking yourself which subject you are in all help. If the problem persists, the university counselling service can help. Last updated: November 2026.
Key points
- Strong exam anxiety can disrupt how the brain processes information.
- A blockade usually does not mean the knowledge is gone.
- A short three-step routine helps during the exam: reduce adrenaline, relax, encourage yourself.
- You may ask the examiners to repeat the question.
- In written exams, start with easier tasks and note keywords for difficult questions.
- If blocking happens regularly, use the counselling services of your university or Studierendenwerk.
What happens during a blackout?
The counselling service explains that strong exam anxiety can disrupt information transfer in the brain. The details are then not retrievable in the moment, even if you knew them well before. This explanation does not replace a medical diagnosis. It helps you place the moment in context: a short block is unpleasant, but it does not mean you have forgotten the topic.
Why do blackouts happen in exams in particular?
The counselling service links blackouts to strong exam anxiety. This is an explanation from counselling practice, not a medical diagnosis. Time pressure or the feeling of being watched can increase tension. Being aware of this helps you classify the moment when it happens.
The difference between forgetting and blocking matters. When you block, the knowledge is still there, but it is hard to access at that moment. This distinction takes pressure off, because you do not have to start learning again. You only regain access.
What do you do immediately in the exam?
The Psychosocial Counselling Service recommends a three-step routine that reduces tension and helps you find the thread again. It works for written exams and oral exams alike:
- Reduce adrenaline: deliberately drop something and pick it up again. If panic is strong, stand up briefly, go to the toilet and move.
- Relax: tense your muscles briefly and release them. Breathe slowly into your belly, for example with a lip brake.
- Encourage yourself: think of one concrete, credible positive thought, such as a topic you know well.
How do you address the examiners?
In oral exams you can say openly that you have lost the thread or that you are suffering from exam anxiety. You can ask for the question to be repeated. Alternatively, work on another question and return to the open one at the end. This approach helps because you do not have to hide the situation and can still carry on.
How do you find your way back to the topic?
A simple technique is to orient yourself. Ask which subject and which part of it you are in, and what else you know about the topic. This activates the knowledge connected with it. In written exams, start with the easier tasks and note keywords on a scrap of paper for difficult questions. Practising the technique beforehand makes it faster to use in the exam.
What helps before the exam?
Preparing for the moment is part of exam preparation. The table shows what is useful at which point in time.
| Timing | Action | Purpose |
|---|---|---|
| Weeks before | Practise the three-step routine out loud at home | The sequence is familiar when you need it |
| Weeks before | Decide how you will phrase a request for repetition | You do not have to find the words in the moment |
| Days before | Sort the material by subtopic | You know where you stand in the topic |
| On exam day | Breathe calmly before entering the room | You can use the technique before tension rises |
| During the exam | Easy tasks first, keywords for difficult questions | You collect knowledge instead of getting stuck |
Which checklist helps on exam day?
A short list relieves you, because you do not need to think about everything on site. These points have helped many students:
- A note with the three steps of the routine, without any study material.
- ID, writing equipment and permitted aids ready, as stated in the exam notice.
- A formulation for requests in your own words, ready in your head.
- Before starting, breathe out deeply once and loosen your shoulders.
- After a blackout, switch tasks and start with easier questions.
Frequently asked questions
Is a blackout dangerous?
A blackout is a temporary block and not a danger in itself. It is still unpleasant and can recur. If exam anxiety strongly affects your studies, talk to a counselling service about next steps.
Must I stop the exam if I block?
Usually not. Whether you continue, apply for a special arrangement or withdraw from an exam is governed by your university’s examination regulations and the examination office. Clarify these questions in advance.
If you are unsure how your examination office handles a blackout, ask before the exam date. Many offices can explain the options in a short conversation, and the answer is more useful in advance than during the test.
Does deep breathing really help?
The counselling service recommends slow belly breathing as part of the three-step routine. There is no guarantee, the exercise is meant to lower tension. If you practise it at home, it becomes easier in the exam.
Practise the breathing and the three steps on a few different days, so that they feel routine by exam time. Repetition matters more than a single good attempt.
Where can I get help at my university?
Many universities and student welfare organisations offer psychosocial counselling. The Psychosocial Counselling Service of the Studierendenwerk Göttingen is at Goßlerstraße 23 in 37073 Göttingen. On the website of your own Studierendenwerk you will find the services in your city. Study groups and tutorials at your university can also help reduce pressure before exams.
