One-week revision

How to revise in one week when you've left it late

With seven days left, the deciding skill is not revision technique, it is triage — choosing what not to revise. A week gives you roughly 30 usable hours. A full module contains far more than 30 hours of material. Every plan that tries to cover everything ends the same way: three days of thorough notes on the first two topics, four days of panic, and an exam sat on a quarter of the syllabus you happened to reach. The plan below assumes from hour one that you will abandon material, and makes you choose which, while you still can choose.

Day 0: two hours of triage before any revision

Do not open a textbook yet. Spend the first two hours building a map, because every hour after this one is spent according to it.

  1. 1

    List every topic on the syllabus, one line each

    From the module outline, not from your notes — your notes only contain the lectures you attended. Twenty to forty lines is normal.

  2. 2

    Score each topic out of 5 for how likely it is to be examined

    Evidence, not vibes: how many past papers featured it, how many lecture hours it got, whether the lecturer said "this is important". Weight past papers heaviest — see how to use past papers.

  3. 3

    Score each topic out of 5 for how well you know it

    Be brutal. "I attended the lecture" is a 1. If you cannot explain it out loud right now, it is at most a 2.

  4. 4

    Rank by (likelihood × gap) and draw a line

    Multiply likelihood by (5 minus your knowledge). Sort descending. Draw a hard line under whatever fits in 30 hours — realistically 10 to 14 topics. Everything below the line is abandoned, deliberately, in writing.

  5. 5

    Write the abandoned list somewhere you'll see it

    This sounds like a formality and is the load-bearing step. Unabandoned material comes back at 11pm on day 5 as guilt and eats the evening you'd planned for the topics that actually matter.

The seven days

DayFocusThe output that proves you did it
1Top 3 ranked topics. First pass: read once, then self-test.One blank-page brain dump per topic, plus a question list for each gap.
2Next 3 topics, same method. Review day 1's gaps first (20 min).Three more dumps. Day 1 gaps re-tested and mostly closed.
3Next 3 topics. Review days 1–2 gaps first (30 min).First full past paper attempt, open-book, untimed, in the evening.
4Remaining topics above the line. Mark day 3's paper properly.A marked paper with your losses categorised: knowledge, technique, or time.
5Second past paper, closed book, strictly timed. Then fix what it exposed.A score, and a list of the three topics it proved you still can't do.
6Those three topics only. Plus one more timed paper if there's time.Everything above the line has been tested at least twice.
7Review only. No new material. Finish early, sleep normally.One pass through every brain dump and every gap card. Stop by 8pm.

Why past papers move from day 6 to day 3

The instinct is to revise first and test at the end, when you'll do better. That gets it exactly backwards. A past paper on day 3 is a diagnostic — it tells you which of your remaining four days is being spent on the wrong thing, while you still have four days. A past paper on day 6 is a score you can no longer act on.

Sit the first one open-book if closed-book would produce a blank page. The purpose is not the mark; it is discovering that question 4 requires a technique you have never practised.

How to actually spend a revision hour

Each topic gets roughly two hours. Split them like this, and note how little of it is reading:

  • 15 minutes reading the notes or chapter, once, with a pen. Not three times.
  • 20 minutes blank-page dump — write everything you know about the topic without looking. This is the actual revision.
  • 10 minutes checking against the source, marking only the gaps.
  • 45 minutes on questions — past-paper questions on that topic, or generated ones if you've run out.
  • 10 minutes converting the gaps into questions you'll re-test tomorrow morning.

If you find yourself re-reading for an hour because it is comfortable, you have reverted to the illusion of fluency and the week is being spent. The discomfort of the blank page is the signal that it's working.

Sleep, and the day-7 temptation

Every hour you take from sleep this week costs you more than it gives, with one exception: if the exam is tomorrow and you have genuinely not covered a major topic, an extra two hours tonight is worth it. That exception does not apply on days 1 through 5, where lost sleep degrades tomorrow's encoding and quietly makes the whole week less productive.

Day 7 should end early. Reviewing until midnight the night before feels responsible and reliably costs more marks in exam-hall attention than it adds in recall — the arithmetic in all-nighters is the same one day out.

If you have three days, not seven

Same method, harsher line. Rank the topics, take the top five, and run days 1, 3 and 5 of the plan above compressed: triage, two topics a day with testing, one timed past paper on the middle day, review on the last. Do not attempt breadth. Five topics known well outscores fifteen topics recognised, on almost every mark scheme ever written.

Common questions

Is one week enough to revise for an exam?

Enough to pass, and often to do well, provided you triage. Seven days gives roughly 30 usable hours, which is far less than a full module — so the plan has to start by choosing what to abandon. Students who fail a one-week revision aren't usually short of hours; they spent them evenly across material they couldn't cover.

How many hours a day should I revise in the last week?

Four to six hours of genuine testing-based work, not twelve hours of reading. Beyond about six hours the return per hour collapses, and the sleep you take to buy hours seven and eight costs you more than they produce. Consistency across all seven days beats two heroic days and five broken ones.

Should I do past papers or revise the content first?

Both, but start past papers by day 3 rather than saving them for the end. An early paper is a diagnostic that redirects your remaining days; a paper on the last day is a score you can no longer act on. Sit the first one open-book if that's what makes it possible.

What should I do the day before the exam?

Review only — no new topics. One pass through your brain dumps and gap questions, one look at the formula sheet or key definitions, and stop by early evening. New material on the last day is rarely retained and reliably raises anxiety, which costs more than it gains.

How do I decide which topics to skip?

Rank each topic by how likely it is to be examined multiplied by how large your gap is, then draw a line under what fits in your available hours. Likelihood should come from past papers and lecture emphasis, not from how interesting the topic is. Write the abandoned list down — undecided material eats evenings as guilt.

Is cramming for a week actually effective?

For the exam in seven days, yes — massed practice does produce short-term recall. For anything cumulative later in the course, no: most of it is gone within weeks. If the same material is examined again in finals, plan on relearning it, and consider putting the core facts into a spaced review queue now so you don't pay twice.

Try it on your own material

Upload your notes, slides or lecture recordings and get a tutor that answers only from them — and says so when they don't cover it.
