For exam revision

Revision is not re-reading. Here's what to do with the six weeks

Most revision fails in a specific and predictable way: it consists of re-reading, it feels productive because the material becomes fluent, and fluency is mistaken for knowledge right up until the moment the paper is turned over. The fix is not more hours. It is a different activity — and a schedule that decides what you do today so you don't spend the hour revising what you already know.

The four moves, in order

  1. 1

    Get everything into one place, and find the holes

    Every slide deck, reading, recording and photographed page for the module. Then generate a study guide — its gap list tells you what your material doesn't actually cover, which is the thing you most want to discover in week one rather than week six.

  2. 2

    Take a diagnostic quiz before you revise anything

    It will be unpleasant and it is the most valuable hour of the six weeks. You cannot allocate revision time sensibly until you know where you are weak, and your intuition about that is reliably wrong — you feel weakest at the topics you dislike, not the ones you're actually failing.

  3. 3

    Convert every wrong answer into a flashcard

    Now your deck *is* your weak areas. Review it on the FSRS schedule and the algorithm decides what you see today. You have outsourced the one decision people get catastrophically wrong.

  4. 4

    Sit past papers under real conditions

    Timed, closed book, no phone. Then generate more questions in your exam's format when the real ones run out. Everything you get wrong goes back into step three.

Why cramming feels like it works

Because it does — for about seventy-two hours. Massed study produces a real, measurable spike in recall, and if your exam is tomorrow, cram; it is the correct move and anyone who tells you otherwise is being ideological. What it does not produce is a memory that survives to the second exam of the week, or to the year you actually have to use the material. Spacing the same total hours produces dramatically better retention at essentially no extra cost. The research is unusually one-sided: cramming vs spacing.

The hour before

Do not learn anything new. The marginal fact is worth nothing and the anxiety costs you real marks in the first twenty minutes of the paper. Review the cards that are due, look at the structure of your study guide once, and stop. The focus dock in Thaxas has a breathing exercise for exactly this hour, which sounds absurd until the morning you need it.

Common questions

How far in advance should I start revising?

Sooner than feels necessary, because the benefit of spacing compounds and cannot be recovered later. Even a light review habit that starts six weeks out beats an intense one that starts two, for the same total hours.

Is cramming ever the right call?

If the exam is tomorrow, yes — massed study genuinely does spike short-term recall, and pretending otherwise is unhelpful. It just doesn't build anything that survives the week.

How do I know what to revise?

Take a diagnostic quiz before you plan anything. Your sense of your own weak areas is unreliable — people conflate 'topics I dislike' with 'topics I'm failing'. Let the score tell you, then let the scheduler allocate the hours.

How many hours a day should I revise?

Fewer than you think, more consistently than you manage. Two focused hours of retrieval practice beats six hours of re-reading, and the second is what most revision timetables are secretly made of.

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.
