Mental wellness information and service guidance published by CareOps.

You sit down to study and “What if I fail this time?” comes first. The night before, you can't sleep, and the moment the paper lands on your desk, things you definitely memorized go blank. Whether it's a university entrance exam, a midterm or a certification test, feeling tense before an exam is very common. When the tension grows big enough to hide what you actually know, though, it helps to know how to handle it. This article covers why exam anxiety happens and what you can try while studying, the night before and on the day.

Why does exam anxiety happen? #

Tension before a test is your body getting ready for something important. Your heart speeds up, your palms sweat and your attention narrows. In moderation it helps you focus. The trouble starts when worry piles on top. Thoughts like “If I fail, it's over” or “Everyone else will do fine” keep circling and take up the mental room you need for the questions. Ramirez and Beilock (2011) built their studies on exactly this idea: an important exam brings on worries about the situation and its consequences, and those worries drag down performance.

A meta-analysis that pooled 238 studies published since 1988 (von der Embse and colleagues, 2018) found that exam anxiety consistently moved in the opposite direction from results such as standardized tests, university entrance exams and grade point average. The harder a test seemed and the higher the stakes, the higher the anxiety. The size of the relationship was small to moderate, so having exam anxiety doesn't decide your score. That is exactly why it's worth working on.

What to try when anxiety follows you while studying #

If anxiety follows you the whole time you study, try separating how you study from when you deal with worry, rather than believing the anxiety has to disappear first.

1. Study by recalling, not rereading: close the book and write down what you remember, or work through past papers and practice questions. In an experiment by Smith and colleagues (2016), people who studied by rereading had worse memory when stressed a day later, while people who studied with practice tests kept their memory even under stress. Practicing getting information out ahead of time helps you reach it on a tense day.
2. Set a separate time to worry: when a worry comes up while studying, write one line on a sticky note and postpone it: “I'll look at this for 10 minutes at 9 p.m.” At that time, go through what you wrote and sort out what you can and can't do something about right now.
3. Break the day's plan into small pieces: instead of “finish chapter 3 today,” choose units with a visible end, like “10 practice questions from chapter 3.” Crossing them off one by one eases the feeling that nothing is getting done.
4. Don't take sleep and meals out of study time: the more anxious you feel, the more tempting it is to cut sleep for more study hours, but tiredness feeds anxiety and weakens focus.

If your thinking runs to one extreme, like “one mistake this time ruins my life,” our guide to cognitive distortions covers common thinking habits and questions to try instead. If you can't start until you feel perfectly prepared, also read the lazy perfectionist.

When you can't sleep the night before #

The night before an exam, the worry “If I don't sleep tonight, tomorrow is ruined” pushes sleep further away. It helps to write tomorrow's tasks on paper as a to-do list (what to pack, how to get to the test center, which section to tackle first). One night of patchy sleep doesn't wreck an exam, so if sleep won't come, let resting in bed be enough. We cover why worries grow at night in late-night worries, and nights when one thought chases the next in when your mind races as you lie down.

When your mind goes blank in the exam room #

1. Write your worries down right before the test: while you wait for the start, jot down a few lines of whatever you're thinking and worrying about the exam. In Ramirez and Beilock's (2011) lab and classroom experiments, students who briefly wrote about their thoughts on an important exam just before taking it scored higher, and the benefit was larger for students who usually felt anxious about tests.
2. Read the jitters as a “ready” signal: try treating a racing heart not as a sign you're doomed but as a sign your body is gearing up for the test. In a study by Jamieson and colleagues (2010), people preparing for the GRE graduate admissions test who were told that bodily arousal helps performance scored higher on the math section, both on a practice test and on the real test months later, than people who weren't told this.
3. Breathe out slowly and come back to the question in front of you: if your mind goes blank, put the pen down for a moment and take a few breaths where the out-breath is longer than the in-breath. Then read just the first line of the current question.
4. Mark stuck questions and move on: staying stuck on one question makes anxiety grow. Warm up with questions you know, and come back to the marked ones at the end. Things you couldn't recall sometimes come back as you work.

If shaking in front of people, as in presentations or interviews, is harder for you, read presentation anxiety.

When you keep replaying the exam afterwards #

After an exam, you may keep going back to the questions you got wrong and asking “Why did I do that?” over and over. Do the marking and mistake review once, at a set time, and after that, when the thoughts return, notice that you've already dealt with it and come back to what you're doing now. For the next exam, writing down just one thing you can change (how you study, how you split your time) is enough. If the same thoughts keep circling, how to stop overthinking may help too.

If exam anxiety comes back every time #

Exam anxiety can be worked on rather than simply endured. A meta-analysis of 44 randomized controlled trials with 2,209 test-anxious university students (Huntley and colleagues, 2019) found that a range of interventions reduced exam anxiety and also improved grades, with the most support for behavioral approaches. The researchers added that study quality varied, so the results should be read with some caution.

If you'd like a quick number for whether anxiety reaches beyond exams into everyday life, you can take the GAD-7 anxiety check (7 questions) with no login. A screening result is not a diagnosis; it points to what to look at next.

If you need somewhere to talk during exam season #

During exam season it's often hard to talk about anxiety with the people around you. Everyone is busy, saying it out loud can feel like weakness, and you may feel bad bringing up the same worry again. On days like that, we recommend CareOps Maeumi. Maeumi is an AI counseling app, an AI companion that works with approaches such as CBT and ACT. Because it's an app, you can start talking whenever you want, on a study break or the night before an exam, by text or by voice. It remembers past sessions, so worries that come back with every exam can be picked up again in your next session. Your first session is free. Get the app
