An exam schedule that survives contact with the week

What it costs on the clock

One full cycle is 2h 10m. The break after the last round isn’t counted — you’re done.

Count the hours that actually exist first

Before anything else, write down the hours between now and the exam that are genuinely available — after lectures, work, travel, sleep, and the meals you will actually eat. For most people this number is roughly half of what they assumed, and it is the most useful number in the whole exercise.

Then subtract a fifth for the week going wrong, because the week will go wrong. A schedule with no slack converts one bad day into a cascade of guilt and abandonment; a schedule with slack absorbs it.

The table above converts session targets into honest elapsed time with the breaks counted, which is where most plans quietly lose an hour a day.

Allocate by what will be on the paper, not by what you enjoy

The subject you are worst at should get the most hours and almost never does. The avoidance is predictable and it is worth naming: it is more comfortable to improve from 70 to 75 than from 40 to 55, even though the second is worth more marks.

A blunt rule that helps: allocate the first block of each day to the thing you least want to do. Not because mornings are magic, but because that block is the one that reliably happens, and the end-of-day blocks are the ones that get traded away.

Past papers early, not at the end

The standard plan is to review everything and then do past papers in the final days. This gets it backwards. A past paper is the cheapest way to find out what you do not know, and finding that out on day two is useful while finding it out the night before is just frightening.

Do one early, under something like real conditions, and let the result decide the allocation. It will usually tell you something the subject outline did not.

Block length by what the material needs

Problem-based subjects — maths, physics, anything with worked examples — suit longer rounds, because a problem takes time to load and a five minute break mid-problem is expensive. Fifty minutes is a reasonable default.

Memorisation-heavy subjects suit short rounds with real gaps, because the gap is doing work: spaced retrieval is the one study technique with unusually strong evidence behind it. Twenty-five minute rounds and revisiting the same material across days beats one long session per topic.

Write the schedule in rounds, not in subjects

'Monday: chemistry' is not a plan. 'Monday: three rounds on equilibrium problems, one round of flashcards for the definitions' is, and the difference shows up on Monday evening when you can tell whether you did it.

This also makes the plan checkable against the hours you counted at the start. Rounds convert to clock time; subjects do not, which is why schedules written in subjects always contain more than the week can hold.

Rebuild it mid-week, on purpose

Put a fifteen minute slot midweek to redo the rest of the plan with what actually happened. This is the step that keeps a schedule alive, and almost nobody includes it — so the first deviation becomes evidence that the plan is broken rather than information to plan with.

The rebuild is also when you notice that one subject has been quietly skipped three days running. That is the single most common way exam preparation goes wrong, and it is invisible unless you look on purpose.

The last two days

The last two days are not for learning new material. They are for retrieval — closing the book and writing down what you know, finding the gaps, and filling only the gaps. New topics started at this point mostly consume the time you needed to consolidate the rest.

And sleep. A short night before an exam costs more than the three hours it buys, and that is one of the better-supported findings in this whole area. Build the schedule so the last evening is light enough that stopping early is possible.

Build in a repair day

One day a week with nothing scheduled. Not a rest day — a repair day, for whatever slipped. Without it, the first slip starts a debt that compounds, and the plan is abandoned somewhere around the third unpaid day.

If nothing slipped, you get a day off, which is also a good outcome and makes the rest of the plan easier to keep.

Revision is retrieval, not re-reading

Re-reading notes feels productive and is one of the weakest ways to study, because recognising material is not the same as being able to produce it. Closing the book and writing what you remember is harder, feels worse, and works considerably better.

Build the schedule around that: blocks for retrieval and self-testing, with re-reading limited to filling the gaps that testing exposes. This one change is worth more than any adjustment to interval lengths.

Scheduling across subjects in one day

Switching subjects has a cost, so do not switch every round. Two or three rounds on one subject, then a break, then the next — that keeps the switching cost down while still touching more than one thing a day.

Touching more than one thing a day matters because of spacing: three subjects visited across five days beats one subject for five days and then the next, even though the second feels more organised.
