By Cyril KimbiThe last week before an examination is when most candidates do their worst revision. They panic, open the syllabus at chapter one, and try to cover everything — which guarantees that nothing is secured and that they arrive exhausted.
Why starting a new topic now is a bad trade
A topic begun in the last week will be shallow, unreliable under pressure, and will consume time that could have moved a shaky topic to secure.
The arithmetic is straightforward. Six hours spent half-learning something new might earn a few marks if it appears. The same six hours spent drilling three topics you nearly know converts them into reliable marks across every question in which they feature.
There is one exception: if a topic is guaranteed to appear and you have nothing at all, learn the minimum — the definitions and one worked example. Not the whole topic.
The seven days
| Day | Focus |
|---|---|
| 7 | Full past paper, timed. Mark strictly. This produces the week’s priority list. |
| 6-5 | Drill the top three losses from that paper. Retrieval, not reading. |
| 4 | Second full paper, timed. Compare the losses to day 7. |
| 3 | Drill what still recurs. Draw every diagram from memory. |
| 2 | Light: definitions, formulae, diagrams. Half a day only. |
| 1 | Skim your own summary sheets. Pack everything. Stop early. |
Notice that two of seven days are spent sitting complete papers. That feels like a lot and it is the correct allocation: a timed paper is simultaneously practice, diagnosis and rehearsal of the actual conditions.
Retrieval, not review
Re-reading notes in the final week produces a strong feeling of familiarity and very little recall. That feeling is precisely what fails in the hall.
Everything in the last week should be production from memory: write the diagram on a blank page, then check; state the definition aloud, then check; do the calculation without looking at the formula sheet, then check. If you are looking at anything while revising, you are not revising.
The one-page summary sheet is the right artefact for this week. One page per subject, written from memory, containing only the things you keep forgetting. Rewrite it daily and it gets shorter — which is itself the measure of progress.
Sleep is part of the preparation
Memory consolidates during sleep. Studying until two in the morning actively undoes part of what you did that evening, and it degrades the reasoning and recall you need the next day.
Two nights before the paper matters as much as the night before, because that is when the accumulated deficit shows. Keep the schedule you will need on the day, and shift study earlier rather than later.
The same applies to eating. Sitting a three-hour paper on an empty stomach is a self-inflicted handicap.
The day before
Do less than you want to. A half day of light review, and then stop.
Pack everything the night before — identification, admission documents, pens, spare pens, ruler, calculator if permitted, and a watch. Every item hunted for in the morning is a small dose of adrenaline you cannot afford. Confirm the centre, the time and how you will get there.
Avoid the corridor conversation about what everyone else covered. It has never helped anyone, and it reliably manufactures panic in candidates who were fine.
If you are badly behind
Then the last week is a triage exercise, and triage means choosing deliberately rather than reading faster.
Identify the topics that appear on every paper — past papers tell you this in an hour — and secure those completely, ignoring the rest. Covering 60 percent of a syllabus reliably beats covering 100 percent superficially, because the exam rewards what you can produce, not what you have seen.
And make sure the guaranteed marks are safe: definitions, formulae, labelled diagrams, the first parts of structured questions. Those are available regardless of how much of the syllabus you have covered.
Frequently asked questions
Should I cram the night before?
No. It adds very little and costs sleep, which is where the day’s learning is consolidated.
How many hours a day in the final week?
Four to six focused hours, with real breaks. More than that in the last week usually reduces performance.
Is it too late to improve?
No. Converting nearly-known topics into reliable ones is exactly what the last week is for, and it moves grades.
Should I do past papers or revise notes?
Past papers, timed and strictly marked. Notes only to fix what the papers reveal.
What if I panic in the paper?
Put the pen down for twenty seconds, breathe out longer than you breathe in, and move to a question you can definitely do. Success restores capacity — see the guidance on exam anxiety.
