Imagine you’re in the middle of an exam and suddenly your mind goes blank. You know that you studied, you remember reading that answer, but now there’s no way to find it in your brain. Meanwhile, you feel the pressure of time, sweaty hands and, to make matters worse, you realize you need to use the bathroom.
Why does this happen? Why did you remember everything at home and in the exam it seems your brain blocks?
The following video will help you understand what happens to your brain in this situation. Pay attention to how the character reacts when entering a state of stress and how their memory is affected.
What Happened to Your Brain in an Exam?
During an evaluation, your brain processes many things at the same time:
- Read the questions and retrieve the stored information.
- Manage time pressure.
- Deal with the stress of wanting to do well.
- Control physical distractions (like noise or the need to use the bathroom).
When stress is too high, the amygdala (the part of the brain that detects threats) activates and blocks the prefrontal cortex, which is responsible for remembering and reasoning clearly. It’s as if your brain entered “survival mode” and decided that the most important thing is not the exam, but dealing with the threat it perceives.
Why Do We Remember Better at Home?
When you study in your room, your brain is relaxed. It doesn’t feel pressure, can take its time and the hippocampus (the region that stores memories) works without interference. But in an exam, conditions change:
- There is a time limit.
- Social pressure affects you (comparing yourself to others, fear of failure).
- Your body reacts with physical stress (tension, sweating).
This doesn’t mean you don’t know the answer, it means your brain can’t access it at that moment.
5 Strategies to Avoid Freezing on an Exam
- Practice under controlled pressure. Instead of always studying in a calm environment, do practice exams at home with limited time. This way, your brain will get used to working under pressure.
- Breathing before the exam. Before you start, take 5 deep breaths (inhale 4 seconds, hold 4 seconds, exhale 6 seconds). This reduces the activation of the amygdala and allows the prefrontal cortex to function better.
- Start with what you know. If you freeze on a question, skip it and answer first what’s easiest for you. This generates a sense of achievement that reduces stress.
- Reconstruct the context. If you can’t remember something, think about where you were when you studied it, what was around you or what image the page had. This activates the hippocampus and can help you retrieve the information.
- Talk to yourself (silently). Telling yourself phrases like “I can do this” or “I’ll go step by step” can reduce anxiety and improve performance.
Final Challenge
In your next exam, try at least two of these strategies and then reflect: Did you notice any difference in how you felt and in your performance?
