How to study for finals in one week

By Planr.ai · 6 September 2026 · 6 min read

Seven days is enough time to do well in most subjects and not enough time to do everything. The plan below assumes you are starting from behind, because almost everyone is.

Day 1: find out what is actually on it

Before you study anything, spend one hour working out what you are being tested on. Not what the course covered — what the exam covers. Those are different, and the gap is usually two or three whole units.

Get the exam format in writing: how many questions, what type, how long, what weighting. A 90-minute paper with four essays needs a completely different week from a 90-minute paper with sixty multiple choice. If the teacher has not said, ask. Most will tell you, and the ones who will not usually let something slip when asked directly.

Then list every topic and mark each one A, B or C. A means you could teach it. B means you recognise it but could not produce it from memory. C means you do not really know what the words mean. Be honest here. Marking a C as a B is the single most common way this week goes wrong, because you skip it, and it appears on the paper.

Days 2 to 4: work only on your Bs

This is counterintuitive and it is the highest-leverage decision in the week. Your Bs are the topics where a couple of hours moves you from half-marks to full marks. Your Cs need five hours each to reach the same place, and your As need none at all.

For each B topic, do one thing: close the book and write down everything you know about it on blank paper. Then open the book and mark what you missed in a different colour. That gap is your revision list. Reading the chapter again is not — you will recognise every sentence and conclude you know it, which is precisely the illusion that produces a bad grade.

Three days of this, four topics a day, is twelve topics converted from half-known to solid. In most courses that is the difference between a C and an A-minus.

Day 5: past papers, under time

Sit one full past paper with a timer and no notes. Not a practice set, not the questions at the end of the chapter — the real thing, at the real length.

This is uncomfortable and that is the point. You will discover two things you cannot discover any other way: which topics collapse under time pressure, and whether you can physically finish. Running out of time is a skill problem, not a knowledge problem, and it is fixable in a day once you know you have it.

Mark it strictly. Give yourself nothing for answers you would have got “if you had more time”, because on the day you will not.

Day 6: the Cs you cannot avoid

Now go back to the C list, and only to the ones the past paper proved were unavoidable. Some Cs never come up. Those stay unlearned, and that is a correct decision, not a failure.

For a topic you genuinely do not understand, find one worked example and copy it out line by line, writing next to each line why that step happened. If you cannot say why, that is the exact sentence to ask about. One good question to a teacher is worth three hours of rereading.

Day 7: do almost nothing

Review only your own notes from the week — the gap lists, the marked past paper. No new material. Nothing you learn on day seven will survive to the exam, and the attempt will cost you sleep, which will.

Sleep is not a wellness suggestion here. Memory consolidation happens during sleep, so the studying you did on days two to four is finished overnight, and cutting that short partially undoes the work you already paid for.

What to cut when the week is already gone

If you are reading this with three days left, keep days 1, 2 and 5, and drop the rest. The order that survives compression is: know the format, convert your Bs, sit one timed paper. Everything else is optional.

Do not make new flashcards in the last week. Making them feels productive and is mostly transcription.
Do not colour-code anything. Time spent on the appearance of notes is time not spent retrieving from them.
Do not study with people who are more behind than you are. You will spend the session explaining, which helps them.

If keeping track of what is A, B and C across five subjects is the part that falls apart, that is the job Planr does — it holds the topic list per class and what is due when, so the week is a sequence of decisions rather than a scramble to remember what exists.

Two mistakes that cost the most marks

The first is spending day six making materials. New flashcards, a fresh mind map, a rewritten set of notes — all of it feels like progress and none of it is retrieval. By day six the only thing worth doing is answering questions with the book shut.

The second is studying in the order the exams happen. If the Monday exam is your strongest subject and the Wednesday one is your weakest, Monday will eat the week anyway because it is closer. Allocate by weakness and weighting first, then protect a short block for the closest exam so it does not swallow everything.

What to do when two exams land on the same day

Split the day before in half, and give the larger half to the paper with more marks available, not the one you are more worried about. Worry is not a measurement. Then stop early enough to sleep, because the second exam of a double day is lost to tiredness far more often than to ignorance.

If the two papers are in different subjects, do not alternate every twenty minutes. Switching costs more than it looks — give each one a block of at least ninety minutes so you get past the reloading phase.

The last twelve hours

Read your own summary sheets, do a handful of the questions you previously got wrong, and stop. The evidence on sleep is not subtle: a tired brain retrieves worse, misreads questions, and makes the mechanical errors that a rested one catches. Trading three hours of sleep for three hours of revision is a bad trade on the night before, whatever it feels like at midnight.

Pack everything the night before — calculator, pens, ID, water — so that the morning has no decisions in it. It sounds trivial. Arriving flustered costs marks in the first ten minutes, and the first ten minutes are usually the easy questions.
