Name your situation in two numbers
Two numbers place you before any playbook opens. The first is how much time is left: a night, a week, a month, a season. It says what is possible. A night holds one retrieval pass and no spacing; a week, one wide pass and one deep. A month holds the whole campaign; a season, the campaign and a life around it. The second is the score you want. It says what counts as done, subject by subject. Pass is every topic at not-zero and the repeating questions cold; strong is solid and connected where the marks live; top adds the rare corners and your own errors.
Every playbook is the same five moves with those two dials set: decode the shape, aim the hours, run the passes, practise in the form, rehearse the day. A plan only says something once it names what each sitting retrieves, how the sittings are spread, and where the check comes from — never a count of hours. Find your cell, run it, and when the numbers change, change cells.
Right now, write your own two numbers for one subject: how many days to the exam, and whether you are aiming to pass, to be strong, or for the top. Say the sentence out loud. That is the playbook you need to open next, not a longer list of hours.
Stopping to name two numbers feels like time I could already be studying.
Naming them is a short job, and it decides the rest of the night. Without it you might re-read a subject that is already solid while a shaky one goes untouched, or aim for the top in a subject the date will not allow. The two numbers are not delay — they are what turns the hours you do have into the right list.
Set the target per subject, not per self
A target is not one number for you; it is one number per subject, and the numbers should differ. Your total is a sum, and a mark costs more the higher you already stand in that subject. The climb from blank to passing is cheap; the climb from strong to the top is dear. So the cheapest marks on your whole table sit in your lowest subject that still counts, and the dearest sit in the one you like most. Set each subject’s target from what it is worth to the total, where you stand now, and how far the date lets you climb.
Read the target as a depth rule, not a mood. Pass means every topic at not-zero and the repeating questions cold, nothing polished. Strong means solid and connected everywhere the marks are, then stop. Top means strong first, then the rare corners a pass target skipped and the errors still costing you, lost more to slips than to gaps at that height. Ninety-five in one subject and a pass in another is not low ambition; it is the same hours placed where they buy most.
Right now, list your subjects and, next to each, today’s honest standing and the date’s honest limit. Circle the one where the next mark is cheapest, usually your weakest subject that still counts, and the one you are tempted to over-polish. That pair is where your hours should move first.
Setting a pass target for a subject feels like I have given up on it.
It is spending, not giving up. A pass target still puts every topic at not-zero, so nothing is a blank; what it refuses is polishing a subject whose next mark costs three of another’s. Raise the target the moment the date and your other subjects allow it — the target is a decision about hours, not a verdict on the subject.
The gap follows the date
Both claims about cramming are half right. The best gap between two sittings of the same topic is a slice of the time left to the date. About a day when the date is a week away, and ten days at a month. About three weeks at two months, and still three weeks at a year; the slice shrinks as the date recedes. Below the slice you are massing and the second sitting adds little; above it you have forgotten too much to retrieve. Tomorrow’s exam wants no gap, and that cram is gone within weeks; an exam six months off wants three sittings three weeks apart, which beat nine in one weekend.
One rule sets the time axis for every playbook: count the days to the date, take the slice, and space your returns that far apart. Spacing’s rule that gaps should widen each time still holds; the slice only bounds how wide they may grow for this date. A longer date buys wider gaps, never more hours. The cram is a tool with a range, not a sin and not a method.
Count the days from today to your next exam in one subject. Find where that falls on the scale — about a week away, a month, two months, or longer — and write down the gap in days it points to. That number, not a feeling, is how far apart your next two sittings of that topic should sit.
Spacing sittings three weeks apart feels slower than cramming nearer the date.
It only feels slower because cramming looks like more work packed into less time. A cram sitting for a distant exam is gone within weeks, so you pay for it again later. Three sittings three weeks apart beat nine in one weekend: fewer hours, placed where they survive to exam day. A longer date buys wider gaps, not more hours.
Tonight: the exam is tomorrow
One night is left, and the exam is tomorrow morning. You cannot learn anything new tonight. You can only pull out what you already have, choose what is worth pulling, and protect the hours you need to sleep. That is the whole job: what to retrieve, what to skip, when to stop. Three moves decide tomorrow’s score, in this order of weight: what you produce from memory, what you spend the evening on, and whether you sleep. Nothing else tonight moves the number. If tomorrow is a skill test, there is nothing to pull out. The evening is one short timed set, then the list, then sleep.
The run-list opens with the paper, not because it weighs most but because everything after it depends on it: one past paper says which topics still carry marks, so the evening goes to the shaky ones that matter, not the ones you already know. Then retrieval, and it takes most of the evening, because it is the move that actually shifts tomorrow’s score; reading it all once more feels most like studying and moves the score least, so producing cold comes before you can talk yourself into re-reading. Sleep comes last, because a tired head cannot pull tomorrow what a rested one can.
The day between two papers is this same playbook, run for the next paper only. And a cram works for tomorrow and is gone by next month: tonight serves the date, not the subject. If the same subject has a later date too, the returns start the week after.
- Open one past paper. Read it for two things only: the shape of tomorrow’s paper, and which topics carry the marks. Do not sit it; there is no time to mark it tonight.
- Close the book. For each high-value topic the paper marked shaky, produce it from memory before you open anything. Mark every hole you find, in a different colour.
- Check the solid ones. Give each high-value topic you already know one cold check, nothing more. For the rest, glance only at the questions that repeat.
- Write the fear list. In the last hour, write down what you most fear forgetting. Keep it short enough to read once in the morning and empty onto the margin.
- Then go to sleep. A night awake costs more marks than it earns, and leaves you sure you did well when you did not. Close the list and go to bed.
Right now, pick the subject you are weakest in for tomorrow. Turn the book face down. Give yourself four minutes to write everything you can produce on one topic from that subject — formula, steps, the diagram. Then open the book and count what came back against what you missed. That count is tonight’s real score, not the hours you have put in.
If I sleep, I lose five hours I could still spend revising tonight.
Those five hours would have gone to re-reading, and re-reading is the pass that moves the score least — most of it would not have stuck by morning. Sleep instead, and you keep the head that has to pull everything out tomorrow morning, under time pressure. Students who stay up score lower on average and feel more certain they did well, which is the worst combination. Write the fear list, then go to bed.
One week: wide once, deep once, two papers
A week is what you have left, long enough to build something real and short enough that one wrong order wastes it. In this stretch you get exactly two passes over your material and two attempts at a full paper — no more, however hard you push. What you skip is a decision: a week cannot hold a syllabus at depth, so it holds all of it at not-zero and the marks-heavy half at strength. The order below decides which topics get which pass, and it is the whole week.
The map comes first. A week spent guessing where the marks are is a week half wasted, and one past paper sorts every topic into its cell before anything else happens. The wide pass follows, because a blank topic scores zero however deep your best three are, and it is the cheapest marks the week can buy. The deep pass then returns to the same list about a day after each topic’s first return, which is what the date allows. It closes the holes the wide pass marked and rehearses the paper’s own form. Day seven is tonight’s playbook, run once more. A check from outside your own head closes every day, because a week gives no room to repeat a mistake twice.
- Map the week. Sit one past paper cold on day one. Name the shape, sort every topic into its cell, and write down the shaky-and-valuable list — that list is the week.
- Run the wide pass. Over days two to four, take every listed topic to not-zero, one sitting each, produced from memory and not read. Mark every hole you find.
- Run the deep pass. On days five and six, return to the same topics in a new order, deeper where the marks are. Sit one paper under the clock, marked to the scheme.
- Close with tonight’s playbook. Day seven is the night before, run again for this paper alone: retrieve, triage without mercy, then sleep.
Right now, if an exam is a week away, sit one past paper cold, closed book, no notes, and time yourself. Mark it against the answer key and sort every topic it touched into a cell: solid, shaky, or untouched. That sorted list is the shaky-and-valuable list day one asks for.
Spreading three days across every topic feels risky when some are far weaker than others.
The wide pass does not treat every topic equally — it only guarantees none is a blank, which is the safest floor a week can buy. The deep pass on days five and six is where the weak, marks-heavy topics get the extra return; the wide pass is what earns you the right to spend those two days there instead of firefighting a topic you never touched.
One month: the campaign, with a clock on it
A month is the first stretch long enough to hold your whole campaign, if you run the numbers honestly from day one. You can decode the exam properly and work every high-value topic to solid and connected. You can still sit a full paper each week under the clock. The month’s discipline is stopping. A topic reaches solid and connected and you leave it, because the next mark there costs more than the first mark in a topic you have not opened. The plan starts with an estimate, because every month feels like plenty in its first week and never is by its last.
Week one estimates before it plans. Two papers set the shape, and every topic gets a time taken from what one like it cost you before, raised by a third for the optimism in the number. The wide pass runs through weeks one and two so the high-value topics reach solid ground before the deep pass has anything to deepen. The low-value ones are left at not-zero on purpose. Weeks three and four return every topic about ten days apart, mixed rather than blocked, and a paper a week keeps the form current. The last day is tonight’s playbook, unchanged.
- Map and estimate. In week one, sit two past papers, sort every topic into its cell, and time each one from what a like topic cost you before — then add a third.
- Run the wide pass. Across weeks one and two, take every high-value topic to solid and connected, produced and checked, the holes logged. Leave the low-value topics at not-zero.
- Run the deep pass. Weeks three and four: return to the same high-value topics ten days apart, mixed, not blocked. One full paper a week; sort each lost mark: did not know, slipped, out of time.
- Finish with tonight’s playbook. The last day of the month is the night before one paper — run that playbook for it, unchanged.
Right now, pick one topic and time how long it actually takes you to bring it to solid and connected, not your guess, the clock. Multiply your whole list by that number, add a third, and see whether the days left cover it. Most months do not close in week one.
Admitting the calendar will not close in week one feels like giving up early.
It is the opposite — it is the plan working as a month is supposed to. Nobody’s calendar closes in week one; the estimate is always short, because every topic is cheaper to imagine than to actually reach solid and connected. Finding that out early leaves three weeks to triage. Finding it out in week four leaves none.
A season: the campaign, and a life around it
A season is three months to a year, and it fails in a different way from a week. It is not for lack of a plan, but for lack of the days themselves. Nothing about the plan is hard to write; what is hard is still doing it on day sixty, on a bad week, in the middle of other subjects. What counts as done still runs pass, strong or top. But a season is the one stretch long enough to actually test whether your method holds, not just whether the syllabus gets covered. Start it late and it quietly becomes a month, and a month cannot hold a year’s syllabus at the depth a top target needs.
The campaign comes first, at full size, because a season is long enough to run every trunk move properly. The shape is decoded on day one rather than the last month. Three passes return about three weeks apart, and a timed paper comes every fortnight from the first month, its lost marks sorted. But a plan this long survives only if something carries it day to day, so the second half is the life. One defended window, anchored to something already in your day, carries it. The streak is counted rather than the mood, and one small experiment on the method runs each month, judged only by the recall it moved.
- Decode the shape early. Decode the shape on day one, from the notice and one past paper, not in the last month, while three-week gaps are still cheap to run.
- Defend one window daily. Anchor one study window to something you already do every day, and keep it small enough to survive a bad day rather than skip it.
- Run three spaced passes. Return to every topic about three weeks apart, wide, then deep, then in the exam’s own form, across the full length of the season.
- Count the streak, not the mood. Track whether the window happened, never how it felt. Keep a one-page system for the plan and a card for the days it slips.
- Sit a paper each fortnight. From month one, mark every timed paper to the scheme and sort each lost mark, and re-cut the calendar at every month’s end from what actually happened.
- Run one experiment a month. Change one thing about how you study, run it for a month, and judge it only by the recall it moved, not by how it felt.
Right now, write down the one daily window you can defend for the whole season, the same slot after something you already do, and name what it is anchored to. Then write one thing you will change about your method this month and how you will judge it.
A season is so long that skipping a week here and there should not matter.
One skipped week rarely breaks a season; skipping being the plan does. The habit that carries this playbook is the streak, counted in windows kept, not in how urgent any single day felt — and a season started late quietly becomes a month, which cannot hold a year’s syllabus at the depth a top target needs. Protect the window before protecting the topic.
No date: the season without the papers
Some readers open this book with no exam waiting for them: a hobby, a language for its own sake, a subject picked up after college. The two numbers that place everyone else, the date and the score, are simply not there, so the first job is to write them yourself. Pick a date and keep it the way you would keep a board’s own date. Then build a test you can genuinely fail. It might be a paper of your own making, a recording judged against a model, a page written from memory and checked, or a problem set attempted cold. What counts as done is no longer a score; it is a performance you name before you begin.
Once the date and the test exist, this runs like a season. The shape is decoded on day one, in the same four questions, read off the notice you wrote instead of a board’s. A wide pass comes before a deep one, spaced by the date you chose rather than an official calendar. A cold test comes every fortnight, marked against something outside your own head, its misses sorted the same way a timed paper’s would be. Writing the target down first matters because a target you can adjust as you go is one you will always meet. The life around it does not change: one defended window, anchored, the streak counted, one experiment a month.
- Set your own date. Choose a date for the performance you want, and keep it exactly as you would keep a board’s, not movable when the week gets hard.
- Build a test you can fail. Decide the form: a paper you write, a recording judged against a model, a page from memory checked, or a problem set attempted cold.
- Write the performance down first. Before you begin, write what you will be able to do at the date that you cannot do now — that sentence is the target.
- Decode the shape. Answer the four questions from the notice you wrote yourself, the same way a board’s notice would be read on day one.
- Run wide, then deep. Take every topic to not-zero before returning to any of them a second time, spaced by the date you chose.
- Sit a cold test each fortnight. Mark it against something outside your own head, and sort every miss the way a timed paper’s misses would be sorted.
Right now, for one thing you are learning with no exam attached, write a date and one sentence naming what you will be able to do by it: a page from memory, a piece you can play, a conversation you can hold. Then decide the test that would prove it.
Without a school or a board behind it, this stops feeling like real studying.
The two numbers made it studying in the first place, not the board that supplied them. Write your own date and keep it, build a test you can actually fail, and the season runs exactly as it did with an exam; the only difference is who wrote the notice. What breaks it is comfort, not the missing board: a stalled season means the test was too soft or the date was not real. Fix those before touching the method.
Just pass: the marks on the floor
When the target in a subject is to pass, you are collecting the cheapest marks on the paper, on purpose. Two past papers show where those marks sit. The question types that appear every year, the topics that are never absent, and the short questions that pay by the point. Done here is coverage, not depth. Every topic gets touched once, the repeating types come solved cold, and the words, formulae and dates that carry marks on their own get learned by heart. Nothing is polished, nothing is read twice; the hard corners are left at not-zero and no deeper, and that is the plan working, not a shortfall in it.
Coverage comes before depth because a pass target pays for breadth, not polish. Every topic gets one cold production so nothing is left blank, since a blank scores nothing. The repeating question types get practised in their own form until they come cold, because two past papers show which ones return every year. The by-heart facts go in alongside them, since they pay marks on their own, and rote wins exactly here. In the room, writing to the scheme lets a half-known answer take its half of the marks, which is exactly what a coverage target is built to collect.
- Take every topic to not-zero. Give each topic on the syllabus one cold production, from memory, so that no question on the paper is left a blank.
- Drill the repeating question types. Find the question types that come every year from two past papers, and practise them in their own form until they come cold.
- Learn the by-heart facts. Commit the words, formulae and dates that pay marks on their own to memory — rote is the right tool exactly here.
- Write to the scheme. In the exam room, answer in the scheme’s own words so a half-known point still earns its half of the marks.
- Attempt with the penalty rule. Attempt everything on a paper with no penalty; on a penalised paper, attempt only what you can eliminate down to.
Right now, for a subject you are aiming to pass, open one past paper and mark every question type that repeats from earlier years. List the topics those questions come from — that list, not the full syllabus, deserves your time first.
Leaving the hard chapters out on purpose still feels like cheating myself.
It is spending, not cheating. The pass target already decided that the next mark in this subject costs about three of another’s, and the hard chapters are where that cost is highest. Every topic still reaches not-zero, so nothing is left as a blank — that is your insurance. Depth on the hard corners is a different target, for a subject with the hours.
The top: the last ten marks are errors
By the time a subject is solid and connected everywhere the marks are, the marks still missing are rarely about what you do not know. They are lost to slips, to time, to a misread question, and to the rare corner that appears once in five years. Some are lost to answers that knew the point and never wrote it in the scheme’s own words. The playbook for a top target starts exactly where the strong playbook stops, and it runs on a log, not a syllabus. At this height everyone in the room already knows the material. What separates the top score is errors and time, not knowledge.
Every timed paper is marked to the scheme and every lost mark sorted, because each class has its own fix. Did-not-know sends a topic back to the deep pass and opens the rare corners a pass target rightly skipped. Slips get drilled as a type, confident wrong answers first, since a mistake you were sure of is the one most likely to stay corrected once caught. Time is fixed by a budget per question and two passes over the paper. Misreads and unshown work are both fixed by writing to the scheme. A paper a week, the log re-read before each; the measure is the same class of error not appearing twice running. Polishing what already scores is still the loss it always was.
- Mark to the scheme. Score every timed paper against the official scheme, not your own sense of a good answer, so every lost mark is real.
- Sort what you did not know. Send that topic back to the deep pass, and now open the rare corners a pass target was right to skip earlier.
- Drill your slips as a type. Practise the confident wrong answers first — a mistake you were sure of is the one most likely to stay corrected once caught.
- Fix the time you lost. Set a budget per question and run the paper in two passes: what comes at sight first, the slow ones after.
- Fix misreads and unshown work. Reread the command word before answering, and write every step in the scheme’s own words so the marker can see it.
Right now, take one marked paper back and sort every lost mark into one of five classes: did not know, knew and slipped, ran out of time, misread, or knew and did not show it. Count which class costs you most.
Keeping a log of every lost mark feels slower than just doing more papers.
More papers without the log repeat the same errors, because nothing tells you which class they belong to or whether your fix worked. The log is written once, after each paper, and pays for itself the first time a mistake does not reappear. At the top, the measure is not how many papers you sat; it is the same class of error not showing up twice running.
The grid: twelve cells, one line each
Four times, three targets, twelve cells, one per subject. Tonight barely changes with the target, since a night can only protect: retrieve the repeating questions, the shaky-and-valuable ones, or everything, cold, then sleep. A week: map, then wide pass, stopped at not-zero, or deepened on the marks-heavy half, or logged from paper one. A month: the campaign with a clock — the wide pass alone, or the whole campaign at ten-day returns, or that plus the rare corners. A season: a light campaign and a habit, or the campaign at full size at three-week returns, or that plus the log and the corners.
Two rules run through all twelve. The gap between returns is a slice of the days left, so a longer date buys wider gaps, never more hours. And the target is set per subject, so you can stand in three cells at once. Find your cell, run its line, and move when the numbers change — the grid was always scaffolding for the retrieving.
