The Final 48 Hours — Last-Minute Preparation That Helps

The 48 hours before an exam are not the time for heroic last-minute cramming. They are the time for consolidation, preparation, and rest. What you do — and do not do — in these final hours can make a significant difference to your performance.

48 Hours Before: Smart Consolidation

What TO Do

Activity	Time	Purpose
Review your summary notes or flashcards	1-2 hours	Refresh key facts and formulae
Read through one mark scheme for a recent past paper	30 min	Remind yourself what examiners reward
Review your "common mistakes" list	15 min	Prime your brain to avoid your known errors
Check your exam logistics (see below)	15 min	Remove any logistical anxiety

What NOT To Do

Activity	Why Not
Learn new topics from scratch	Not enough time for encoding + consolidation. Wastes time better spent on topics you already know.
Complete a full past paper	This is for weeks before, not hours before. It will reveal gaps you cannot fill and increase anxiety.
Revise for more than 3 hours total	Diminishing returns. Your brain needs rest to consolidate.
Stay up late studying	Sleep is more valuable than the last hour of revision. Always.

The Exam Logistics Checklist

Logistical problems on exam day create unnecessary stress. Eliminate them in advance:

Equipment Checklist

Item	Check
Black pens (at least 2 — one may run out)	Packed
Pencil (for diagrams) and sharpener	Packed
Ruler (for graphs and diagrams)	Packed
Calculator (for maths and science — check the battery)	Packed and tested
Eraser	Packed
Transparent pencil case (required by most exam centres)	Items transferred
Water bottle (clear, with label removed)	Prepared
Watch (not a smartwatch — analogue or basic digital)	Set to the correct time

Logistics Checklist

Detail	Confirmed
Exam time and date	Double-checked (not just from memory — check the timetable)
Exam room or seat number	Confirmed
Route to the exam (if not at your usual school)	Planned with extra time
What to wear (uniform requirements?)	Laid out
Who is driving you / how are you getting there?	Arranged
Contingency plan if something goes wrong (alarm does not go off, traffic jam)	Considered

24 Hours Before: The Final Day

Morning (1 hour maximum of study)

• Review your key formulae, key dates, or key quotations — the things that are easiest to forget and most useful to have fresh
• Use flashcards for a quick active recall session
• Focus on your weakest topics for a brief refresher — 15 minutes maximum per topic

Afternoon (No study)

This is counterintuitive but important: stop studying by early afternoon the day before the exam. Research consistently shows that:

• Material studied the day before an exam benefits most from a good night's sleep for consolidation
• Continuing to study late into the evening increases anxiety without significantly improving recall
• Physical activity in the afternoon (a walk, a swim, time with friends) reduces cortisol and improves sleep quality

Evening

Activity	Purpose
Have a proper dinner	Nutrition affects cognition — eat well
Prepare everything for tomorrow (bag, clothes, route)	Remove morning decisions that add stress
Relaxing activity (TV, reading, music — not social media)	Wind down your brain
Avoid exam discussions with friends or parents	Do not let someone else's anxiety become yours
Go to bed at your normal time	A consistent bedtime supports better sleep than an artificially early one

If You Cannot Sleep

• Do not panic. One night of imperfect sleep does not significantly impair exam performance.
• Get out of bed if you have been lying awake for more than 20 minutes. Do something boring (read a dull book, not your notes) until you feel sleepy.
• Do not look at your phone or revision notes. The blue light and the content both increase alertness.
• Focus on breathing: slow inhale for 4 seconds, hold for 4, exhale for 6. Repeat.
