The night before the exam

Exam stress · 4 min read · By the MajorMind team · 16 October 2026

It's 11 p.m. The exam is at 8:30. Part of you says "one more hour". Here's what the research says about that hour, and how to spend your last evening.

Sleep is part of studying

While you sleep, your brain doesn't switch off: it replays and strengthens what you learned during the day. Researchers call this memory consolidation (a good overview: Diekelmann & Born, 2010). Skipping sleep means skipping that step.

A short night also makes the next morning harder: slower thinking, weaker attention, more careless mistakes, exactly when you need them least. One more hour at midnight rarely pays back what it costs at 8:30.

A calm last evening

1. No new chapters. Review what you already know, by testing yourself: a blank page of the main topics, your list of mistakes.
2. Prepare everything for the morning: student card, convocation, pens, calculator, water. Check the time and the room.
3. Stop at a fixed time, and put the phone away a little before bed.
4. Go to sleep. What you learned earlier is being stored tonight.

Stressed? Write it down for 10 minutes

In a study published in Science (Ramirez & Beilock, 2011), students who spent 10 minutes writing about their worries just before an exam did better than students who didn't, and it helped most those who were the most anxious. The idea: worries take up space in your working memory. Putting them on paper frees some of it for the exam.

It works the night before or the morning of: write freely about what scares you, without judging it. Then close the notebook.

A kind reminder

If you couldn't study everything, that's normal: almost nobody does. Tomorrow, start with the questions you know best. And if stress feels too heavy, talk to someone you trust.

MajorMind does this for you: your exam page has a night-before checklist and an "I'm stressed" button for a calm minute when you need it. Free.
