No. All-nighters consistently hurt exam performance more than they help. Sleep is when your brain consolidates memories, so staying up to cram actively undoes the revision you have just done. Students who sleep seven to eight hours the night before score measurably higher than those who sleep fewer than five, even if the latter revised more. If you are behind, accept it, do a focused 30-minute review, and go to bed. Walking into the exam rested beats walking in with extra content and brain fog.

Focus on three things only: past papers under timed conditions, targeted review of the weakest topics those papers expose, and exam technique around command words and timing. Do not try to learn new content in the final week. Instead, cement what you already know and sharpen how you deploy it under pressure. Spend half your time doing papers and half reviewing mistakes against the mark scheme. Keep a running list of the silly errors you repeat, then eliminate them one by one.

Seven to nine hours a night, consistently. Teenagers and young adults need more sleep than adults because their brains are still developing, and sleep is when information moves from short-term to long-term memory. Revising until 1am for a week straight will cost you more marks than the extra hours gained. Aim for a regular bedtime, avoid screens for an hour before sleep, and keep caffeine to before noon during exam season. Treat sleep as part of your revision strategy, not a luxury.

Eat a proper breakfast with slow-release carbohydrates and some protein, things like porridge with banana, wholemeal toast with eggs, or yoghurt with granola. Avoid sugary cereals that cause a mid-exam energy crash. Drink water but do not overdo it, you do not want a toilet break during a three-hour paper. Take a bottle of water and a small snack like a cereal bar or piece of fruit if your exam allows it. Do not try anything new or unusual on exam day.

Put your pen down, take five slow breaths, and move to a different question you can answer. Coming back to the tricky question later with a calmer head almost always helps. Examiners mark every question independently, so getting stuck on one does not affect your marks elsewhere. If you still cannot remember something, write down anything related to the topic, partial credit adds up. Practise this in your timed past papers so panic recovery becomes a trained response, not a first-time reaction in the exam hall.
